Domain listing services, an alternative to auctions and brokers, are websites which allow sellers to list and sell their domain names in a DIY-type environment.  Usually, no commissons, but also much more limited services.

Examples include DotComerica.com, 100domains.com, DomainsListing.com, MAXdomains, alphanames, and many more.

Similarly, many domain name forums offer one or more message boards with the express purpose of allowing users to list their domains:  Digital Point, SitePoint, NameCheap, SiteUSell, etc.

We thought this was a nice idea in principle, but not really the best location to solicit buyers for a premium domain name.  Sales from domain listing services and online forums seem to mostly be in the $xx-$xxx range...
