The guys from fanadventures.net launched their website 2 weeks ago. Their goal is to offer a place, where adventure developers can discuss and host their projects, no matter which engine they use.
They opened a subforum for each known adventure game engine and there is also one for adventure maker.

There are no entries yet, but if anyone wants to discuss AM in german, this could be the place.
