What Has Happened to My Template?!

I have been attempting to make some improvements to my template such as adding social bookmarking buttons, making sure the subscribe by e-mail box actually works, etc. But something has gone wrong somewhere because sometimes (not always) it does very strange things. So apologies for that - at least the posts themselves are not affected. I am going to try and put it right over the next few days. I think it will be a case of going back to the original template that I downloaded and starting again! Wish me luck!!!
