MoinMoin Contrib
By now there are a lot of MoinMoin extentions on the markets. These are provided by users and are not maintained by the MoinMoin developers. A large number of them will not get into MoinMoin because they need external programs, are for intranet only or are simply too special. Nevertheless they are useful (and some of them are really cool 
).
Idea: Make a contrib directory within MoinMoin to include plugins that are not active per default but maintained by the MoinMoin developers.
