If you have turned on email notifications for PM's this will send out an email when you receive a private message.
If you reply to that message you will (more than likely) get this response:
"When replying to email notifications from the GWTW Forum you need to log into the forum and click on the "MY MESSAGES" tab in the top navigation bar (http://www.gwtwforum.com/index.php?action=pm
) or email the person directly.
Replying to the notification sends the email to Forum Admin."
While I enjoy getting email as much as the next guy
... I may not always be timely in bouncing back this email to you. I know a lot of you use the PM function for swap meet dealings and I would hate to see a deal soured by the incorrect usage of PM's. Also, you may not want me to reading your "private messages".
