Question about using vbulletin

i just got the vbulletin forum and i know nothing about PHP :slight_smile: but i was able to set everything up with the install, etc and the forum works fine. but i have a few questions on customizing it like Kirupa’s forum.

How does Kirupa get the forum sections categorized?
How does he get the Moderators names bold in the who’s online panel??

i know these are newbie questions but i checked the Main CSS section in the admin control panel and i cant seem to find where i could adjust this?
