Free domains from Domain Lagoon

Domain Lagoon offers free domains to its members (USA only). From their website:

Our program has been founded by a few private individual who thought it
would be great to offer free domain names once again. This has not occured in
years. Yes many web hosts and other sites offer free domain names when you
signup for their package or pay a year in advance. We offer you a domain
absolutely free. The domain is registered in your name so you retain full
ownership of it after completing our program! We even provide you a full
management console to control the domain from. We have all the same features
that you would have if you ordered your domain name from one of the big
expensive site.

You can check this site and search your domain here.
