OK, this is getting annoying, and anyone that knows how to contact google let me know - the help pages are a maze of twisty turny passages all alike.
The blog is now on http://revk.www.me.uk/
I wanted it to be on http://www.me.uk/ but the do not allow on "naked domains"
However they do allow the naked domain to work with A records, so example.com would work as well as www.example.com. Great.
So www.me.uk has the A records, but does not work. My guess is a bug in google seeing www and stripping it to find the blog. But as I cannot say me.uk is my domain (it is not) I cannot make that work.
