I tested this a bit more and the quiet login is working.
The full list:
noWarn
noKick //Just to be complete. Use noBan if you want to protect people from kick votes.
noBan
noMute
noMuteVOIP

There’s another thing that may not work as intended and that might be related to the fact that “noKick” doesn’t do anything. If I join a group that has “noBan” protection but no protection from warnings, I can kick myself by giving warnings with power admin.

Hi DrFunkenstein,
NoKick means that other groups can’t issue a kick for this group.
It works when u use the ingame kick button. Obviously the game sees a voteKick as another command :s
I don’t know for sure what “poweradmin” is? RCON? It’s another kick/ban system then the basic in-game one.

I suggest you try it out. My guess is you can kick anyone that’s logged into one of the groups in your usergroups.dat except the clanleader, he’s the only one with noBan protection. Like I said earlier, I’m willing to volunteer for a kick if someone will move me into one of those groups on your server 
.
Power admin is tool for administering your server. There’s nothing you can’t do with rcon, but it has a nice user interface which makes it a bit easier.

Breo and I did a few tests on the Villa server today and things are a bit different then I thought they were.
The noKick does protect you from kicks by people who have kick rights on the server, but it doesn’t protect you from kick votes, you need noBan protection for that.
Thanks for your help, Breo!
