For the upteenth time, when you log on at MM and next page is the Main Forum page. IF YOU HAVE A PM (INBOX MAIL)THERE WILL BE A RED FLAG AT THE TOP LEFT EDGE SIDE OF THE FORUMS. THEN YOU GO TO THE (INBOX MAIL) JUST ABOVE AND OVER TO THE RIGHT SIDE.
Click on that INBOX and read your mail and then at the bottom of that message you type in your reply and SEND, it goes back to the person you received it from.
IF YOU WANT TO SEND SOMEONE AN PM, just click on the "single image icon" to the right of a persons name and send a PM. The double Image Icon is for e-mail to person.
