Just figured I'd let people know about cleaning out their messaging box if you're hitting your limit.

Go into your private message box, and choose "show messages from [the beginning]" and hit go. You should then see all the messages in your box that haven't been deleted. Select the box for delete next to the messages you want to clear and hit delete. Then select "jump to folder Sent Items" and hit go, then repeat the same process (show messages from the beginning). Once you've got both cleared, you should be good to go.

If theres any trouble with that, drop me an email or a private message and I can take care of it for you.
