Following on from the post I made last night, I was able to get through to the company who deal with my domains and the problem was sorted - apparently it was a fault on their end.
I was really worried that I might have lost the domain. Afterall, I've had it for 6 years now, and I rely on it a great deal, mostly for emails though.
Anyway, changing subject - what do you think of the new Blog template that I have designed? I have tried it out on Internet Explorer 7 and Firefox 2 and it appears to look alright. I had an issue with Internet Explorer 6, but I think it may have had more to do with my laptop than anything else. The template was based on an existing one, but I changed so much of the code that it's almost a complete new design.
I would love to hear any comments on the new design, and for visitors to tell me if the blog doesn't appear as it should on their OS / Internet browser - so please leave feedback (good or bad) and let me know.
