A conflict resolution forum is and always has been a good idea. We haven't implemented it because it requires one or two folks who act as pseudo-professional mediators. They need to have a background/training in conflict resolution, and they have to be committed to visiting the forums and working on these issues regularly. That's a big committment, and one I haven't found any willing volunteers for.

PM status is an easy one, and it now shows in a member's profile if they are accepting PMs or not.
