Well, I guess I could be of some help. I (occasionally) play YGO, although I'm not very up to date with the rules and stuff, cuz I haven't played for a while, so I guess I probably wouldn't be to good for judging, but I could probably help out with some other stuff. I'm (hopefully) going to be cosplaying Isis/Ishizu with a few friends (who may or may not be cosplaying Yugi and Malik), so I would probably fit right in.
But I was wondering what ages you'd want helping (I just turned 15 on the 29). Also, do you know what the schedule is and when the tournament will be taking place? I really don't want to have to miss a panel or event that I'm interested in attending. But if you want my help, I'll do my best.
