* - redirects to appropriate post if only message id is requested.
* - is only used when inside a topic or board.
* - determines the local moderators for the board.
* - adds group id 3 if the user is a local moderator for the board they are in.
* - prevents access if user is not in proper group nor a local moderator of the board.
