Thanks for the input Wizardan. I tried those two just now and they didn't change the area I was looking to change. It's great learning all of these things - as a very new convert to vBulletin, I'm growing to like it more and more.
Anyone know how to change the background or text in the pulldown menu of the top nav bar? "Quick Links" and "Miscellaneous" appear to be in the same font color as the background so they remain basically invisible to the users. I've spent hours trying to track this down (searching here and at vbulletin.com, testing, reading the manual, etc.) with no luck at all.
