I tried to post an item on the auction site and when I click on new topic it says I don't have permission to be on this site am I doing something wrong?

Try this link..

http://auction1.tradgang.com/cgi-bin/ultimatebb.cgi?ubb=forum;f=197

When this opens click on the New Topic button.

Report back if you have problems...

Thank you Bud B.

I had the same problem.  Turns out I was on the 2013 thread which, obviously, is closed.
