at member request, I have implemented private boards, which are boards accessible by certain members or member groups.

Private boards and their topics/posts are completely invisible to non-members.

Additional info:
1) Members who suggest a private board will be made sole moderator over that board.
2) Moderators of a private board may add/remove members by PMing an available admin.
3) Moderators of a private board may delete their private board by PMing an available admin.
4) Members of a private board may delete their membership by PMing an available admin.

I realize having private boards runs contrary to the public nature of forums, and I expect the exclusiveness of private boards will undermine itself by restricting member participation, but I'm curious to see what comes of this, so let's consider this something of an experiment.

If you would like to start your own private board, PM an available admin the board name and group members, or alternatively, make the request by posting said info here.
