Just been playing with OpenID, it's really cool. Looks like to get it working with Hostgator properly you need to request to be white listed as the redirects make mod_security get a little worried. The guys at Hostgator are really helpful thought and I was up and running in no time.

Also I was just thinking that OpenID is a little like the Lord of the Rings, it's the one ID to rule them all. Gekk humour I know. I think it's a cool idea but not too easy to explain to people. I guess in a few years everyone will be using it anyways.
