hey there, I just found this forum and read your thread. I think a JapanWiki like that is a great idea! however I noticed that you welcome page looks bit pixelated and not very modern. since I like designing web sites I want to offer you to remake it (keep the nice language buttons etc. but make it less pixelated and stuff). I'd also like to become an active member of your project, maybe I could write some German articles.
if you're interested tell me so, I'd love to help
however I'm on vacation right now and will be back on thursday.
