I am not sure if I am serious about that idea. It just came to my mind somewhere this evening and I didn´t yet really decide for or against it.
If one could create something like that with only experienced users, it could probably be a great thing for everyone. As one could work out ressources and tutorials for the whole community within a small but kinda professional environment and one could get help with more complex problems easier as it wouldn´t dissappear too fast between all the small problems coming up on these forums.
