Just wanted to say hello! I'm a keen tennis player (been playing for about 15 years now) and an iPhone developer as well. The main reason I registered was in the hope to get some feedback about an iPhone app I've developed for scoring, stat-ing and sharing tennis matches. I'd be happy to post a link to it if anyone's interested, but don't want to do it initially in case that's considered spamming.
So yeah, any regular members or admins care to comment?
I'm also Australian, and hanging out like crazy for the Australian Open!
