I know, dumb question, but how do you delete PM's you've read and don't need to keep AND PM's that I've sent that are unread and I want to delete? Thanks a bunch
When you look at the folders in the private message section, you'll see "check boxes" at the far right hand side of the individual messages. Simply click the boxes for the messages you wish to delete, scroll down to the bottom of the page, and you'll see a box to click that says "delete". Click it... and they're gone!
(You can also use this feature to transer messages to a new or different folder.)
