S.A.Z

I just encountered a reference to the following site.

http://www.s-a-z.de/ SpielAutorenZunft. It appears to be an organization for game designers and authors, and has some pretty big (and some small) names attached to it. It's based in Germany, but with Alan Moon listed as Chairman, it can't be just for Germans.

I really haven't looked through thier site much, but I was curious if anyone is a part of this? If so, what kind of information do they offer?
It says that voting members must have a published game, but the non-published members are support members of some sort (assumably able to get info helping them to publish).
