Blog button?

I've decided that I need a button. I think I'll try to design one when I'm off for Christmas break. I've found some instructions but they all seem a little different. Any suggestions?

This Stupid "Reply" Button!

Ok - I simply cannot figure this out. I can "reply" to comments on other people's blogs but I can't reply to any comments on mine! If I hit the "delete" button it does come up and work (at least I think it would, I always cancel because I definitely do not want to delete anyone's comment) but absolutely NOTHING happens when I hit reply! Does anyone have any ideas? I know it's working for some of you since I've seen some replies posted on other blogs.
