How to make a !muteall command, if not already explained in Tuple's tutorial:
First of all, go to your admin.dat and make a [command] block. This is done by scrolling to the very end, past the bans.
Then, you should type:
[command]
command = MuteAll
exec = exec muteall.cfg
desc = Mutes all the players on the server.
levels = 6 7 8
Since we made the exec field refer to another file, we have to make that file in order for the command to function.
So we would open our text editor and make a file that contains the following:
!mute 1
!mute 2
!mute 3
!mute 4
!mute 5
!mute 6
!mute 7
!mute 8
!mute 9
!mute 10
!mute 11
!mute 12
!mute 13
!mute 14
!mute 15
!mute 16
!mute 17
!mute 18
!mute 19
!mute 20
(Sorry for the long post)
Then, after we rename our document to muteall.cfg and place it in the tremulous/base folder, it should work!
