Hi all, 
Just wondering how to change the colours or user titles (not usernames) ie newbie, Junior poster etc.

Hello
Change hexadecimal color code #xxxxxx

Users & Groups --> Groups --> Options --> Edit Group

Username Style
This option allows you to set a custom username style for users who have this user group as their display group. Use {username} to represent the user's name.

<span style="color: #xxxxxx;"><strong>{username}</strong></span>

Change the star to the icon you want.
