Rob, you're not blocked from anything I know of.
Here's my guess....there haven't been may sale threads lately. When you click on the For Sale section you are seeing threads from the last 30 days (default position0. I'm not sure there's been any. Adjust your category to threads from the last 90 days or 1 year (or something else) and you should find some threads.
Hope all is well with you brutha and wishing you a Happy Holidays.
Mike
