How do I add "Ranks" to my Group?

I've seen Ranks on some groups, such as Venith, and I was just wondering about how I can add them to my own one, *-[3DSiPaint]-*

Idk

LEVEL TEN GYATT

The distinguished DCTheGamr spake:

You can add them via CSS, or if you don't mind them not displaying in shoutboxes, just make a group-page listing the rankings for folks who are noteworthy enough to have one.

Alright! Thanks very much!
