I don't have a ton of experience captaining teams, but what experience I do have boils down to this:
Details will kill you... believe me you will have enough to deal with as a captain without having to wipe your players' a**es yourself.
1) Make them bring their own balls - if adjacent courts have the same number, just have a can or two of spares on you to trade them - if it still is a problem, carry a sharpie and mark one line's balls. This is rarely an issue in my experience, btw. Make both dubs players responsible for a can of balls - this alleviates 99% of the "same number" problems for the dubs lines, and provides spares for any singles that start later. Remind them before every match with your line-up email to do this -
just copy each week's line-up email with these reminders in it, changing only lineup details as needed each match.
2)
Make individuals responsible for refreshments and make sure important things arrive earliest in the day - i.e. water/gatorade/bananas need to be brought by the first couple lines of the day - this is for all seasons, but IN PARTICULAR summer.
Discard any ideas of collecting money from the guys and doing all the refreshment duties yourself. Guys are TERRIBLE at this. YOU may be different, and I know I am different, and would pay happily, but many, if not most, are not different. I had a discussion with another team captain about just this thing and he advocated the "just collect X amount of money from everyone at the beginning of the season and go to Costco and get as many bulk items as you can (cases of balls, snacks, napkins, etc.) and then each week do all the shopping for persishables the night before the match. The players just have to show up, I cover all the balls, all the food, drinks, etc." aproach. I asked him how he arrived at his money figure and he told me that he counted on at least 20% of the people (always men - he ran a mixed and men's dubs team) won't pay, ever, at all... "Oh I'll get you next time, how much is it again?" so he just made the number higher for those who would pay to accommodate those who didn't. After listening to his whole deal on this, I was leaning away from it, despite his enthusiasm for it. So I posed it to my own team and then let the discussion go... questions like "If we all pay, and we don't all play in every match, won't we be getting ripped off?" or "I just bought a case of balls from Costco myself, so can my fee be prorated for the cost of balls?" or "I can bring sandwiches every week, I love to make my own and I make them very cost effectively! You love my sandwiches! Can I not pay?" and "What if I don't like the kind of beer/gaorade/snack/main meal you buy?" and "What about vegan/vegetarian/gluten free/sugar free/low sodium/peanut free/etc. options?" and endless variations on all of those themes... took me about 10 minutes of listening to the discussion before I said "OK, scrap that, we'll assign refreshments to individuals, if you want vegan/vegetarian/sugar free/gluten free stuff, you'll have to bring your own, and you'll be providing the balls for your matches too, don't forget, I'll remind you every week and will expect you to have a fresh can in your bag for the start of every match."
3) Be specific when you tell them to bring refreshments - how many gatorades, how much beer, how many waters, how many bananas, sandwiches to feed X number of people, ICE, COOLER, napkins, plastic utensils, paper plates, etc. It's amazing how many people show up with a 10 lb bag of ice and a case of water and no cooler... seriously.
4) Tell them their start times are at least 15 minutes, if not 30 before the actual start time. This way if one arrives without the ice (and they will), you can tell them to go get a bag from the corner gas station and they won't be late for their actual start time. Further, this accounts for the inevitable lateness that happens now and then to everyone - and that is something that you as the captain don't want to hassle with.
5) As the captain carry a cooler in your car - one of those roughly 48 quart sized sub $20 ones you get at wallyworld - in that cooler, place a gallon size zip log bag of paper napkins and a box of plastic utensils and another gallon zip lock bag of paper plates - this is for when people forget to bring these items and a few spare cans of balls. Keep it all together. Protip: if you have to put napkins out, put them out in that open ziploc bag - this will keep them from blowing away. Protip #2 Paper plates - if they won't fit in a zip lock bag use a rock or something to weight them down so they don't blow away either.

@OnTheLine has great advice in this thread about everything, including the use of the group messaging app - like Whatsapp or GroupMe - took that advice this past season and it has been invaluable! I was already using Tennispoint, and it costs me $25/year, but that is a small price to pay for the conveniences it offers. If you want, try to collect $2 or $3 from the guys to help defer this cost to you, but you will have to make that call. The tools offered by Tennispoint are too numerous to list out, but they are FANTASTIC. I've also used NetLineup and find Tennispoint to be vastly superior to it.
7) Don't play yourself ahead of other players unless you are legitimately better than they are. If you must put yourself in the lineup ahead of better players to ensure eligibility for playoff runs, or the like, make sure you let the players you displace with yourself know why. Last season on my wife's women's dubs team they were playing makeup matches after a rainout. Because of scheduling, these oten get played one line at a time, rather than all lines on a given day... the opponent team was disgusted with their captain who was not a particularly strong player but who put herself at line 1 or 2 every week and lost almost every week. On the particular night that this team captain was playing herself at line 1 against my wife's team's line 1. My wife knows a lot of those other women from other teams and so forth... anyway, almost the ENTIRE REST OF THE TEAM came to watch the match, in their street clothes, during the middle of the week, and they told my wife that they were there to watch their captain get spanked. There were so many of them, I just reheated the boston butt I had smoked for the weekend match which got rained out, and we all made it a party, and the spanking received by the loathed opponent captain was thorough... and I do mean thorough.
8) Write the tiebreaker rules down and any other "tricky" rules (like footfaulting happens when you just touch the baseline, you don't have to cross it to be a footfault) give your teammates copies of it to keep in their bags - this may or may not be as important to your team, but was useful to my and my wife's teams which have had a number of beginners.
9) While it is not exactly the same sort of question, I got a lot of good feedback in this thread:
https://tt.tennis-warehouse.com/ind...reference-cheat-sheet-for-new-players.638400/ there might be some useful things in there that aren't covered here.
10) Team practices and group lessons/clinics - this is a tricky one - Do you just want team practices to be lines playing against each other or do you want them to have instruction/group lessons from a pro included? How much of each? I have seen numerous situations and have seen them each work very well and equally poorly. If you do decide to get into this group lessons, make sure you get your objectives clearly understood and agreed to from your team and potential coach. Also make sure that you have arrangements in place for facilities and ran-dates and so forth, and make sure you collect fees UP FRONT for the whole lesson package (good fkn luck), and if all of that isn't too much hassle for you (for me I've tried it 3 times and it's a brutal hassle, and now any time someone on the team asks about group clinics/lessons, I hand them a business card from one of the coaches I know and tell them they're welcome to set something up if they want to), then I would suggest that you set up group lessons to coach strategy for dubs. I would look into getting coaching on things like how and when to use Aussie and I-formations vs standard, what sorts of shots to approach behind, who covers lobs, when to be two-up vs. two-back, vs. staggered, poaching, net work/volleys, communicating between server and partner, communicating on switches for lobs, point play/king of the court, etc. Most of that won't be ideal for your singles players, but some of them may play dubs too now and then, and might be into it, also some topics (approach shots, net/volley work, chasing down lobs, are still useful for singles players, if not the most efficient use of their practice time. Lessons for individual stroke refinement should be up to the individual players themselves.
