Another Groups Question

I would like to make some changes in the layout of the page that lists all of my groups by categories.  I have a lot of groups and would like to make the font smaller/change the layout somehow.  Where can I find the page with the style etc information for the groups/all page?

Currently, it looks like this:

http://www.medicalspouse.com/community/groups/all

try to use Fire Bug with Fire Fox - it will help you to make this changes.

For example to find size of fonts and color.

Artur

Do you have any idea idea which file that I need to edit?  I've actually never heard of firebug

I believe its in group.css, line 439 or there about
