I recently let drop over 25 freebie.com names including freebiegas. I don't think giving away merchandise, services or advice on the net is a straight nor narrow path to riches. Probably a person with an idea to make a profit from a "free" domain name is unlikely to pay a great deal for the "free' name.
I have never bookmarked an "org" site........I wonder if anyone in the forum knows of a good org site to visit.
Good luck with your names...........
