RWY12 is an "object Placer" tool.. it allows you to add, move, scenery objects (buildings, trees, airport objects like hangars, windsocks). There is the basic program and a set of scenery libraries that contain a lot of objects.
The forums are still there. It looks as though there was a bunch of idiot play that tried to flood the place but if you scroll down a bit in each section you will find the real stuff still in existence. If you're interested in scenery work it's not a bad way to start.
