I'm not sure how many JP101 users live in Tokyo / have visited Tokyo, but...
About two years ago I thought I'd try to create a project that would essentially be a train/subway map of Tokyo--with each station linked to a page containing information and photos about the area. I think I might have some free time this summer to resurrect the project. Would anyone be interested in helping out?--i.e. contributing pictures, writing text, etc.?
