Turn on and off triggers at will, for the host:
"!trig 4 0" to turn trigger ID 4 off,
"!trig 4 1" to turn trigger ID 4 on.
Not that I think nobody has thought of it already ;O


ROCK FUN:
"!trigrock 1"


You could set starting weapons for whenever somebody joins/dies
"!startgun2 50"
"!startgun2 50 PU"
For 50 powered or nonpowered bouncers, if codeable. You could make it ammo, but that is longer.

"!startgun5 red 50"
"!startgun7 blue 25 PU"

Each team gets different starting guns, you could even make levels with no weapons in them be GOOD.
Saying it without a "red" or "blue" would mean for everybody.
