One member with a dealer FFL has received permission to post guns for sale there. He only posts a gun there occasionally. Another dealer posted about 100 in one evening and it was not well received. If you are a dealer you might contact the owner of the site - Dave Webber. You can go to his profile and send him a private message. His email address is in his profile also.
The rules as written at the top of the "For Sale" section are outdated - or at least they are enforced differently than what they are stated to be.
Best,
Mike
