Help - want to add left and right colum?

I want to add Left and Right box for advertisement on forum. I want something like

10% (left colum for adsense)
80% (Forum)
10% (right colum for other adds)

What to do and where to do?

Thanks in advance.

Here are some hacks from vb.org.

I just did a search for side columns and they came up. So if you need more on them try a search and see if they have what you need.
