Rounded Corners Question.

I want to add ro unded corners to the forum. I already have it on the header, but I want to make rounded corners on teh forums part (the part with all the categories, etc.)

How can I do this? can I do this? I once had a layout with the rounded corners, but since it was all CSS, I am not sure how to do it.

I don't know if there is a place in all versions for round corners in the pics management.
I know there is for version 3
use these in the url field
