One topic which is also important did not come up in this thread. The question, wether to restore nodes which were deleted by the original author. We had a lot of this kind of nodes in the "nodes to consider".
In my opinion, this is legally a quite difficult field involving authors right vs. "publisher rights". So in this case before consideration is possible, a clear political decission has to be made. IMHO, this means the rules must be clearly stated in some easy accessible document.
