I remeber a while ago there used to be an area where members could trade or even give away things that were no longer of use to them. I can no longer locate this area, is this contained inside the OMNI domain?

I ask because I have (transferable) coupons that are quite useless to me since they have many restrictions about flying out of hubs (which is where i live) but to someone who does not live near a hub these coupons could be worth upwards of $200. I would rather give them away then have them expire worthless.
