AT&T came today and the guy said that the ADT security system seemed to be the problem. The phone is working again. Still no Internet connection although I can connect perfectly fine with my laptop.
In the midst of all this, I decided to change my blog template (nice timing Phillip!) and of course that hasn't went smoothly either. I have now lost my blogroll and I'm attempting to rebuilt it from memory. If you come across any technical difficulties with the site, do let me know.
In the meantime, if anyone knows how to get the Blogger menu bar back along the top of my site, please let me know!
