I'm very envious of the blogs that have sidebars on both sides. After doing some research and a little Googling, I think I've found directions on how to do it with Blogger. Over the next few days I will be playing around with the code, so if you see my blog going haywire, (hopefully) it will only be temporary.
In the end, if I don't like the way it looks, I may switch to Typepad. Their blogs look really good and you can do more with them, however I would lose all of your great comments. So, if I can make Blogger do more, I'll stay here.
...just givin' my homies the head's up : )
