If you want to see her again next year, you should go to the official A-kon forums and let them know!
she says she would love to come back next year, but it would be up to convention organizers.
if you don't know who she is yet, here's her web site
This year she did panels for international cosplay, cosplay makeup guides, socialogy of cosplay, and more!
I really want her to return, she is such an inspiration!
so if you liked her, go and let them know that we want her back ^ ^
