I recently found out about the Editorial Board and thought it would be a good idea to join. I've done a few doc pages (Directory) but should work on more. This would probably reduce the load in the tw.o forums, which I try to visit daily to answer questions.
My job in real life is working at an advertising and translation agency in Tokyo, where I check copy that's been translated from Japanese to English, write English copy, advise regarding overseas clients, and so on.
