What the Ferret means is that your root,
http://www.nuderotic.com/ should be a hub, and you should build free-sites in directories off that main hub but are linked from the hub.
hub:
http://www.nuderotic.com/
links to freesite:
http://www.nuderotic.com/big-tits/freesite/
links to freesite2:
http://www.nuderotic.com/asian-nudes/freesite2/
etc...
That way you're not locked down to only 1 free-site per domain. Now a few people do use the root for a single free site for various reasons, but it's not a technique for someone new to the free-site game.
