Continuing to think about the romper room, just spitballing.
1) Probies are relegated to the romper room for their first 25 posts.
2) The romper room is only visible to logged in members, including those relegated to the romper room.
3) If a thread is started by a probie and begins to wonder afield it can be locked without explanation, or with, it's up to the admin.
4) The idea of the romper room as I see it, is to keep the probie focused on it's OP, if it strays it is locked without explanation.
5) The rules should be clear, this is your chance DUmmies, don't screw it up by changing the subject. And by the same token, we have to follow the same rules or it's locked without comment.
