WordPress CSS help

Any WordPress/CSS gurus out there? If you look in the right column here, under “My Activism” and ‘My Other Sites’ you’ll see a little diamond before those titles. These are appearing because (I think) it’s displaying unordered lists, yet the next one, ‘Categories’, is displayed the same way and doesn’t display it.

I’ve tried every code permutation I can think of. Anyone know how to make them go away?

“list-style-type: none” appears to be on for them. Also, IE and Firefox put the diamond in slightly different places.

Update: Solved. The WordPress support forum helped me find an answer, which was adding another rule in style.css. (Well, in IE, it now displays a blank yet works perfectly in Firefox, go figure, just a teensy bit more tweaking needed.)
