My Admin name will not change colour

Hi guys

I have looked on here for help, and indeed seen a few posts with this same question.
However nothing I can do will make my admin name appear red, when I'm on the forums.

Home page Here

If you look at the members online, you will see me, "toz", but it is only in the colour of the normal guests.
If you look at the key below it says, Admin should be in red.

So guys, any idea what I'm doing wrong, and why I can not get my admin status to appear red.

thanks

Try creating usergroups instead.

not sure but I think we have a user group and Im in it as admin, but Ill check.
