actually thats not true,
Theres a girl that comes for 2 weeks every year and plays with her uncle (who is one heck of a player himself), and she can absolutely CRUSH the ball on the serve, and has a snake for a second serve, kicks up absolutel huge. OF course she has a scolarship to play tennis in the states, but what you say about women having no serve does not apply to this girl, no sir.
I played her once, because her partner was late, and she wanted to practise her serve. Well to make a long story short i crushed her first seve into the corner, but for 20 mins after that i could get one serve back, and I'm a decent 4.5 player myself who usually reads serves well.
