The forum is full of dead and small posts. A lot of them just being a question, an answear and thats it. Dead post.
A good idea would be to carry any answears and knowledge over to the wiki delete these posts.
Sounds like a great idea.
Many bits and pieces of information are scattered around the forum now.
There is no mention of the beta FBX importer (Ctrl-F7) for example on the Wiki.
Or the flight path recorder (Alt-P), although it does not seem to work at this point.
A list of planned features may also be of interest (clouds, lake support, 3D trees, city generator etc.).
