I have a thread about this too but wanted to make it a wish list item.

I don't see harm in having a place to post a message as vanilla as "I have an M-Audio 61 key controller for sale. Contact me for info."

Nobody is asking PG to broker deals, set up a commerce base... just a place to post a 2 line message for others to see. This would help the newer users getting started that don't have their gear in place yet as well as those who need to sell items to finance upgrades, possibly even purchases of BIAB upgrades.

This would likely be something your average user would use MAYBE 2-3 times in order to give forum comrades first shot before the stuff gets listed on craigslist. It would NOT invite spammers, hackers, or any of the other nefarious activity so many immediately assumed would happen.

Remember, if it goes sour, it can be taken out easier than it went in.
