A direct quote from Zero on another thread regarding a similar situation:

"If you are giving people orders as an admin you need to have the tag on so that they know you really are an admin. People can not be punished for not obeying or respecting and admin that does not have their tag on." -Zero


Basically...an ADMIN does NOT have to wear a tag if he isn't using any (none at all) admin powers. The admin can't make any warnings to other players saying that he will kick/ban them if they do something...they can't kick and/or ban anyone without their tag on...nothing.

So if you see an ADMIN using any powers without the tag on, then ask them nicely. If they don't have their tag on and are not using any powers or acting like an admin to the other players...then that's fine.
