Changing widths?

[butternugsquash]

Wondering how to change the widths of the categories section. I'd like to spread out the category table starting with "Member Galleries" on my site, but I'm not sure where the changes would be made & what they would be. YOu can see it at:

In your Admin => Layout Options try setting your table width to 100%
