Whenever you find something in the depth of this forum, you think to be important or a good discussion of a specific question, please post this link in this thread with a short summary. I will try to give the links some structure and edit this first post ( Admins invited to do as well) .
Plesase do not use this thread to ask for help. Only post the internal forum link when you found something usefull. This way I think we´ll have a nice compendium soon.
