Huh. I just sent you a message on myspace. I've been very neglectful to this site...
Well, I don't know about COSPLAY conventions, but we do go to the large cons a state over that have a LOT of cosplaying going on. Just look at our pics section on our myspace.
So far, we've been to Animazement in Durham, NC and Anime Weekend Atlanta in GA. A lot of great cosplay.
