Help! Why does my blog look weird?

No fair, if there's one thing that I don't like about Macs is the fact that I have to deal with programs that are designed for Windows users. Blek. This sucks, my blog looks fine on my iBook, using Safari browser, but here I am, checking it out on IE at work and everything's all over the place! Is it just me or does everyone see it too?

I don't know, I'm not much of a technie (honestly, do I look like a techno geek to you?) so if anyone has any suggestions of what I can do to fix this - please help!

Q1. How do I spread my page out? My 2 columns are stuck in the center. Ugly la.
Q2. I don't want ALL my post to show on the page - what can I do?
