My website,
www.troupecomique.com is hosted for free on
Website Builder for Website Building - Moonfruit SiteMaker and I have the web address (the troupecomique.com part) forwarded to
troupecomique.moonfruit.com
That way I can use their super easy and nice looking builder while still having my domain address. It's domain forwarding and your host should be able to set that up for you for free if you want it.
Also, I get my domain names from godaddy.com for 9 bucks a year so in case someone is looking for a domain godaddy has a great price!
