I wanna help too as editor. I'm not sure if I'm qualify. I don't have any experience as editor yet but I'm very willing to learn. I know a bit of basic of editing like leveling, cleaning, cloning. But I don't really know about sfx. I can try for a test. I know a bit of Japanese too since I learn some in high school. I would love to contribute something to manga community since I only leech from them so far, I feel quite bad.
I can help proof read too. I'm quite fluent in English and my grammar is not that bad...I think ;p I do know a bit of Japanese since I learn some in high school but I'm not really good at it since it was long time ago since I graduate from school. Just let me know if you guys need my hand, I'll be glad to help out.
