John- take a look under your "User CP" heading in the blue bar. "User CP is the very first heading in that blue bar near the very upper left corner of any page just to the right of the advertisers section.

Click on it and a drop down menu will appear. Read down that menu until you see the sub-heading "Settings & Options".

Click on that and a box will open.

Look for the "Private Messaging" section of that box. The very bottom of that section should be a box to check or un-check to place a "sent " message copy in your "sent message" folder.


Hopefully you will find that box un-checked. Good luck.
