The rules as stated:
Advertisements. If you would like to advertise a
product that your commercial company manufactures, or if you are an
individual private seller, you can buy a classified ad in the magazine
or an ad on the Web site. This includes all buying, selling, and
trading. Any posts that appear to be an advertisement or transaction
will be deleted.
I think the rules, as they've been interpreted in the past, apply to commercial outfits and private dealers. There has always been a little trading of decals and parts and such going on here. Guys helping guys out. Who's going to take out a $10 ad to trade or sell a $5 part?
