Hi Gabby I think your saying about changing the usergroup markup??
From your ACP go to the usergroup Manager and select the usergroup you want to change
3rd option down "Username HTML Markup" in the first box put
Code:
<span style="color:Green" title="Admin"><b>
and in the second box
Thats it, click save and your done, what that will do is Make the Admin a Bold Green Color.
Just do the same for the others, just changing the bold bits below
<span style="color:
Green" title="
Admin"><b>
Have fun
