Welcome to cosplay.com gejen! It's a great site with loads of good people, so use it well!
I myself am 16...so a bit older than most of the people who've posted here! I'm pretty new to cosplay, but have done two so far (most notably Soul Eater Evans from Soul Eater) I'm in Geelong (so Melbourne is my cosplaying area
) I has 1 cosplay friend (yes...I'll use that term :P) in Geelong, but have been productive and formed a cosplay group in Melbourne! So if anyone's interested let me know! Other than that, I'm just happy to talk to people who are into cosplaying and anime and the like, so feel free to chat!
