		- upon successful completion of action will direct user back to topic.
		- is accessed via ?action=notify.

	void BoardNotify()
		- is called to turn off/on notification for a particular board.
		- must be called with a board specified in the URL.
		- uses the Notify template. (notify_board sub template.)
		- only uses the template if no sub action is used. (on/off)
