Removing lines from Sub-categories

I'm running Zen v1.3.9H using the pure black free template at the moment and I want to remove the underscore from the sub-categories in the categories box as well as the sub-categories listing in the main part of the page.

Any help would be appreciated. Thanks

Most of us don't use that template, so a link to the site would be helpful.

Can you suggest any good free templates?

You could add something like this to the stylesheet:

.centerColumn a:link {text-decoration: none;}

and change the red part here to none

A.category-subs, A.category-products {
color: #0075E2;
text-decoration: underline;
}

There are some free templates at (sorry, site offline), but most are variations on the Classic theme. The ones you found at 12leaves or those by Picaflor Azul (available in the Free Software Add Ons) are the best you'll get for free, and you don't want to buy one from Template Monster or Algozone.
