cool cool...so what style do you guy use
I don't play much singles at all, but when I do I usually end up getting the net. As has been mentioned before, serve/volley tennis is extremely effective at the club, and high school ranks because most people are more comfortable standing back and trading groundies. Getting to the net puts pressure on them and takes time away from them.
Only guys with solid technique and spin can pass you if you are any good at it. Most aren't.
I was wondering...what nationality are you all here and is there any system of ranking?
The Admin has been considering, and looking into a country flag by the avatar, but hasn't yet. There are a couple Canadians here, one from the Neatherlands, a handfull from Great Briton, but the rest are scattered about the US.
Don't know what you mean by ranking though.... 
Ranking in tennis, in real life lol, for non professionals.
I suppose that when you enter a tournament, the better you are ranked, the later you start the tournament...so how does this work exactly?
If you peruse the Journal section, you'll get a pretty good idea of where those of us who play, are at in terms of our development.
Most are in the 3.5 to 4.0 area, though in England they have a different ranking system.
A few of our number are playing USTA leagues and tournaments, and some are playing High School tennis.
One guy (Pacer) is out in California trying to get back to playing Challenger Level tennis. That's just below professional level.
There are a few teachers or coaches, and a number of non tennis playing fans.
Hope that gives you an idea.
