Protected Forum

From RPF - The "Script"

Protected forums will be forums that are fully shielded from the game. A Player's profile will not even show up in these forums. Any forum that is protected will act as a normal forum that does not have this MOD installed. No mana cost or restriction, no experience or battles, nothing.

An example of when you would want to have a protected forum is when you have private forums such as moderator or staff forums and you do not want to limit who can post there or do not want those posts effecting the player since the public community cannot see or participate in the forum.
