(I deeply dislike censorship, but here it seems necessary for the sake of overview) This will be copy/pasted into the first post, if the meta-keeper finds it relevant. Everyone is welcome to reply with comments and pointers to things they consider relevant. All should be contained in this first post - which is re-edited regularily. This is a meta-thread, made to allow you to keep track of the posts concerning this single issue - I will continue re-editing this first post. ![]()
