I figured out how to make a three-column blog. It wasn't quite the layout that I wanted, but it will have to do for now. What I like about the new layout is that I am able to separate out the advertising from the links and other related info. The advertising is on the left, the content in the middle and the links and widgets are to the right. Eventually, now that I figured out how to do three-column, I will be adding other features.
Let me know how you like the new layout.
