[SMF 2.0 RC3] How would I go about making a user key?

[Stuck CAPS]

On here, when it shows what users are online, it gives a key of what color is what, and I was wondering how I could do that... Is it a mod, or standard in RC3?  If so, where do I change it/get the mod?

Admin -> Configuration -> Current Theme -> Show group key on board index

Groups need to have a color assigned to them in order to show on the boardindex.

It is standard in SMF 2.0 RC3. ACP > Members >  Membersgroup > Edit Membersgroup. Select group that you wish to modify its color using Hex Color Code like admin #FF0000 that will display admin in red.
