Moving Columns?

By default, there appears to be two columns in the Blog MU Theme. The "skinny" column (aka - Members side bar, Widget Column, etc.) is on the left, while the "wider" content column is on the right. I want to switch this and put the skinny column on the right and the content column the left. I've spent the last 2 days looking and I still can't find a way. Solutions please?
