I expect people will use this forum to run "sealed bid" auctions. To do that, post what you are trying to sell and what your minimum price is. Set a date after which you won't accept any more bids and tell folks how you want bids submitted.

Collect the bids and announce the winner (and the price, if you want) at the end of the auction.

An "eBay" style auction could be run by posting an item and letting folks reply with bids in the thread. I guess.

Please be advised that the neither the forums nor myself are responsible for these transactions in any way. The only purpose is to put buyers in touch with sellers so they can do their thing.

As usual, please don't sell anything illegal.
