I posted to Nifty about y'alls problems getting registered and I'm hoping he can straighten it all out. Why not try the troubleshooting category on here and see if they can help you? Mine went through without a hitch and very quickly, but a lot of folks seem to be having the same problems.
Wow... I don't know what I should be more impressed with:
1) All the amazing posts and ideas already submitted over at www.SufficientSelf.com
or
2) How protective y'all are with making sure there isn't any funny business going on!
