* Private Message Class

*

* $_REQUEST['folder'] display folder with the id used

* $_REQUEST['folder'] inbox|outbox|sentbox display folder with the associated name

*

*	Display Messages (default to inbox) - mode=view

*	Display single message - mode=view&p=[msg_id] or &p=[msg_id] (short linkage)

*

*	if the folder id with (&f=[folder_id]) is used when displaying messages, one query will be saved. If it is not used, phpBB needs to grab

*	the folder id first in order to display the input boxes and folder names and such things. ;) phpBB always checks this against the database to make

*	sure the user is able to view the message.

*

*	Composing Messages (mode=compose):

*		To specific user (u=[user_id])

*		To specific group (g=[group_id])

*		Quoting a post (action=quotepost&p=[post_id])

*		Quoting a PM (action=quote&p=[msg_id])

*		Forwarding a PM (action=forward&p=[msg_id])
