I'm not against the idea, and if such a WikiProject is started, I'll sign up as a participant and put the project page on my watchlist, etc. However, I don't see any particular need for it, or enthusiasm, so I don't think it's really necessary at this time. Some WikiProjects seem to get started needlessly. There is, by the way, already a WikiProject Tibetan Buddhism, but it is mostly inactive. Even WikiProject Buddhism is awful quiet most of the time.—(Talk!·What have I done?)
