Yeah...I'm going to agree that this is pretty plain and simple..while there are servers that don't use tags such as GFL...their way of showing who is admin is not there..
It's rather ANNOYING, that I have NO idea who admin is..you have to play in there enough to know who has admin and who doesn't.
IBIS servers at least say that you're an admin, but in GFL...nothing. Admin names are in color, but that's also for people who donate and people who joined the forums or something?

In the end, having the tag should be necessary when using admin commands. If you don't want to play with it, take it off. Just make sure you have it on when using commands. Even SIMPLE commands.
