It would be really nice if you could see a list of all current members and be able to search for someone. I know you can use the generic search and put in the username and sift through to find a game they were in. However, this doesn't exactly work for someone who just joined and doesn't have any games going on. Plus, if you could just browse users and check out their stuff, that would potentially promote more people and games for those who maybe don't frequent the forums much.
Just my two cents. :)
