I'd like mods / admins to be able to visually identify this group by, for example, a change of avatar background colour or some text string under their username (please don't suggest a custom usergroup title - you cannot wrap conditionals around them!).
However, I don't want anyone else to see this visual cue.
How do I write a conditional that says ...
<if person viewing is a moderator or administrator ... and ... person posting is in usergroup X>
Do this different thing
Do the usual thing
Any help appreciated.
