We are still working on it. Next changes to the PM code:
1) Having a UNDO after pressing DELETE.
2) Deleting PMs older than "x" days and sending the deleted PMs to the member by email.
3) Being able to actually read a portion of the message along with the subject (On the main inbox page). Like that members would have a little preview of the message on the main page.
4) Getting rid of the blinking icon and implementing an easier way to distinguish read and unread messages.
