grief answers to ; by default. Slash commands work regardless of the prefix, so this only changes the message form.
;prefix set !
;prefix # what this server answers to now
;prefix reset # back to the default
Pick something your other bots do not already use. If two bots share a prefix, both answer every message and neither behaves the way you expect.
