I am the founder of Farm Swap America and I am sorry that you had problems registering. It is a fairly new site, so no, not a lot of people are posting as of yet.
If you wish to try again and have problems, feel free to email me at foalfan at yahoo dot com and I will see what I can do to help...
I founded an organization called "Farm Swap America", it's in all 50 states and basically it's a cashless bartering system. Our motto is "Helping Americans, Help Themselves."
Web address is in my signature.

P.S. I just joined this group today, great idea!
