I'm working on and have nearly completed an English navi for 2ch. It's very simple and uses no fancy code, in the spirit of the Futaba Channel navi at http://shii.org/over/futaba which doesn't do much else than translate the menu for you. This navi does a bit more than the Futaba navi though. It presents a specialized vocabulary list which includes not only selected 2ch slang, but also various phrases which can be found on error pages, buttons, links, and the like. It also gives a series of links to various English and Japanese 2ch resources, like the AA Daijiten and the Wikipedia article.

I would like to know if anyone is willing to host such a thing. I presume it will get regular traffic once it's up on a site. It'd need someone who's willing to replace the files from time to time as new boards are added on 2ch and as translations improve and the vocabulary list increases. I can handle email requests and bug reports.
