JMO:
Any commerce related thread started should have a nominal fee charged to post.
It should not matter if one proclaims to be or not to be a dealer,
that ain't the question nor the truth of the matter.
The truth is that people profit here without contributing financially
to keeping the AZB site up and running so that they can continue
to profit here.
Should a nominal fee be imposed on every thread started in
For Sale/Wanted, you will be amazed at the number of nits
that will quit starting threads here.
I'm certain the quality people that enjoy buying, selling, and
trading here would have no problem with a nominal fee.
The nits can go to craigslist.
