Craven, if you would be so kind (yeah! Like you don't have anything else to do!

) Could you explain what limits there are on the PM use?
Who can people "PM" to? Any member?
Can I limit/control who is able to PM me?
Can I tag my out-going messages with a "Return Reciept"? Is there any way to tell if the person I sent a PM to has "Read" the PM?
Is there a limit on the number of PMs I can store in my box? If so, what is the limit and which boxes effect that total? (i.e. inbox, sent messages, Outbox, marked messages, all of the above?)
Can Include Images/attachments in PMs?
I'm sure I (and others) will come up with more questions as time goes on as well. Every board I've used that had PM boxes has recurring questiosn on their use. Maybe if we answer them here it'll give us someplace to point people to!
