Steve, Lakers4Life summed it up.
GSS started a new site for paying members, so the old site is pretty much dead, which is too bad. Lots of great info was shared on that site.
One other note,,,,, the UKRSA also had a great site, which was similar to GSS, but I haven't been on there in a while, so not sure if it has changed as well. It also included a great section for racquet ball and squash.
