I suggest you don't edit your group files manually. Ever. Again. Until you have 1+ years of solid experience in understanding how groups and ULib works in relation to them.
Though you may think you realize what you are doing, you don't as you're breaking the files.
You've added characters to the file that will corrupt the file during read by ULib.
I'd be surprised if you are not getting errors in server console during startup.
General tips to start out, THEN grow your knowledge and custom groups from BEGINNING/EASY growth to more advanced topics.
1)
superadmin is the highest group gmod recognizes.2) You've broken your groups,
recommend resetting them.3) Once reset,
here is how you add yourself as superadmin so the Gmod server, ULib, ULX, and every other common script written for gmod sees you as highest access.
4) If 2 and 3 don't fix you, you must have edited the addons folder files that we actually have printed at the top NOT TO.
See how to uninstall ULib and ULX, then, re-intall, then start at step 3 again.
5) Use XGUI to create groups you want. Not file editing. For inheritance/control there-of, see our FAQ "
How exactly does can_target work?", which also includes very basic inheritance.
The original file snippet you showed was duplicating commands within groups that inherited those same commands from another group. There's no need for that, if they're inheriting a lower group that already has it.
6) If after all that you still have trouble, see
Having trouble with access?
As for nicknames, no, not really. If you have a Sandbox server, you can enable the UTeam function, which lets you rename teams. Those are different than groups though.
And again, only for Sandbox, as every other gamemode has it's own team format.
