I've moved things on a bit and I can now access both my sites with the following addresses.
http://homepage.ntlworld.com/higgsofhambleden/index http://homepage.ntlworld.com/time-to-drive/Index
I'm not 100% sure how I did it but Ikthius put me on the right track.
I'm disappointed however that the addresses are so long and have no relationship to the content. While
www.higgsofhambleden.co.uk still works
www.time-to-drive.co.uk doesn't
How does that affect searchability/ratings with Google?
I'm sorry chickendipper but I don't know what a simple forwarder is. While I've learnt a bit of html the original uploading of my single site was very easy. I've never had to do it again until now and I never dreamt it would cause me any problem until I tried.
