We could make a list here on the forum.
Maybe not on a topic mixed with the others, but on a page dedicated to that, a little like Wikipedia articles : a page that all admins can edit. This "forum" is actually a kind of community site, the forum is only a part of the possible features.

We could add on the site a link to such special pages.
For that I would have to add entries in the menu of the site, though (currently it is missing the stats page for example).
