I think an easier solution would be to keep the
Map database thread up to date. Currently it only has Unkn0wn's maps
If properly updated, I think that thread would satisfy our need for a one-stop map shop.
That said, the ideal solution will be to use the launcher to automatically update people with the latest version of their maps. Either everyone would get all the officially approved maps or people would pick and choose maps and it would work like how firefox 2.0 automatically searches for updates to installed extensions. Though, I think the former would be better because it ensure that everyone always has the same versions of officially vetted maps.
