Karissa Barrows, project manager of the Mass Effect Cast Cosplay Initiative, has created a Facebook group for anyone interested in seeking guidance and entry into the world of cosplaying BioWare game characters:
A community for ALL BioWare cosplayers, cosplay aficionados, and those who want to cosplay but desire a little guidance while starting up. There will never be charters, admins (beyond cleaning up spam and what have you), elitism, or anything otherwise of that nature here. What there WILL be is a group of super fun people who love cosplay and BioWare ready to share their efforts and help with yours.
Thanks to Patrick Weekes for the heads up on Twitter!
