Have you guys created an OOC (out of character thread) in the roleplaying section yet? This would probably help you get more interest by people who want to roleplay. Especially if you have 'Anime' in the name, you would probably get a decent response...
Also, being on topic, I am very new to anime but have started to watched Ergo Proxy and K. They both seem pretty cool especially Proxy as I like the darker style animes over the silly ones (I didn't like Code-Breaker). If you guys have any suggestions on the darker style like Ergo Proxy than any suggestions would be appreciated
