HELP!!!

I have no idea what is going on and I don't know what to do or how to "fix" it. Twice I posted my tonneau cover for sale. I get an email telling me that someone responded to the ad. I go to this site to view the thread and I cannot access the thread and it seems the ad has disappeared. I'm getting very frustrated. I can't seem to find any webmaster/moderator/tech area to reach out to who could help me. I have options to "watch this thread" and "receive email notifications" checked. I'm a registered member. I even uploaded a new pic to my profile last night to make sure and that seems to have worked as it's still there. Can anyone help?
