I stopped by whois just to see who owns the sites. While there I noticed that a few interesting domain names are available for about 10 bucks.
http://www.whois.net/whois/cladforkids.com
clad-for-kids.org is probably a better name for a non-profit and is available.
Also available are;
clad-for-kids.com
clad-for-kids.net
cladforkids.net
In fact, keeping with the spirit of your endeavor, I'll gladly donate today's clad finds to help you purchase a proper domain name. Lets spend 10 bucks and have a bit of fun with the bottom feeder.
