Y'know what, I've been asking the same thing. I'm also from North Wales but I've been having a lot of trouble finding other cosplayers in the area. I know a few local people that cosplay and have even come with me to various conventions. I don't think there are any groups, but that doesn't mean we can't start our own. Perhaps we can talk more on MSN and perhaps meet up. Niccypippy, since you're also local, we could also chat and arrange a meet.
