Powerful and elegant Garry's mod Administration System
There are no menus due to the instinctively named commands.
If the menu is an important part for you, consider using the 1.0 branch.
Keep in mind that there are aliases here, so you can literally write !tp or !tele instead of !teleport.
Aliases have been added to almost every command, so you can write commands on instinct and in most cases they will run.
