I'm currently working on PM's, and I would like to know how status switch from one to another.
I think NEW is for displaying the "you have xxx new messages"
then when you go to your PM box, the NEW messages switch to UNREAD
when you read a message, it is set to READ, and a copy is done with the SENT status.
I believe that SAVED_IN is for saved received messages, and SAVED_OUT for saved sent messages ?
Please tell me if I missed something
