Beat your I-Phone buddies at chess, real time, or via email! ChessMess.Net
My latest project is a chess site that lets you play chess with your friends via any platform. No registration necessary.
You can play on your Droid against a friend with an I-Phone, or even on their computer! Right now the site isn't yet optimized for mobile, but it works well on them anyway. I just beat my brother on his Incredible from my Droid. CHECKMATE!
I'm certainly looking for feedback, so please leave any you have in this thread. I'm hoping to have GO (9x9) up and running shortly.
