Just don't see the harm in having a section to post "I have a 'this' for sale. If you are interested, send me a private message."

Click. Save. Done. No business transacted in public.

What I am suggesting would see no business transacted in the forum, no asking PG to become eBay... just "I have this"....

Whatever. At some point "Because that's the way it has always been" doesn't cut it anymore. Particularly when one user is permitted to include his sales pitch and click through link in his signature file. Forum rule #7 states "Advertising is forbidden in any relation to your account except by explicit permission. This includes, but is not limited to, advertising websites and commercial-related or competing products." If this is a non-commerce site, well......

Maybe someone selling gear could just change their sig to add "Contact me to buy my used 'thing'..."

PS. Everybody defines "spam" differently. I define it as "Shoving your company's advertising down my throat non-stop."
