Where is the best place to sell domain names, preferably somewhere that is busy and perhaps you dont get charged to list it for sale, only if it sells you pay a fee or something, thanks.
The BST section of any webmaster forums you are active on, including this one. It's a free listing, it's interactive, it's simple to take care of, and you'll reach a lot of interested buyers. Otherwise, check sedo.com, especially if you're going to be selling premium domain names.
Also you can try out selling it in popular forum like namepros, dn forum or put a tag in your WhoIs "DomainForSale", even you park it in sedo, it will show " Buy this Domain Name" beside the ad.
there is always the TDNAM - especially if your already a GD user -tons of traffic -true domianers and newBs.
