Unfortunately no, given that CommDay is a server get-together. It wouldn't really be considered CommDay if it was held on the forum, and I don't want to make it too complicated. However, I'll look into hosting more Wi-Fi forum tournaments for people that can't or don't want to access the server. :)
Question, if you cannot get on the PC server for community night, can you participate. Lol my only source of internet is a PSP and a DS, and before training 2 teams I'd like to know if I can even participate.
