Title says all.
I mean the little thing at the bottom of the index that says
Legend: Moderators (an example)

I saw this somewhere before but I cant find it anymore.

Put this in your CSS if you want to hide it yet keep the color

em {display:none}

Go to...Users & Groups // Groups // Group Administration // Modify // Group status // Hidden Group

Thanks mister.
