>I would like to be able to move a thread to another category. That way, If I want to make a joking remark, I can move it to chatter, or if I reply to a newbie about a report question (that was mis-posted under third party products) I can move my reply to the appropriate place.

As Mark mentioned, we can't free this functionality to all. If you see one that should be moved, feel free to email us.
