Forums Scripts & Popups /say command on specified channels only?

I was wondering if there's a way to use /say command only on certain channel that i want it to? I have been trying /say #test,#test2 but it doesn't seems to work. I just need it to execute the command /say on 2 channels instead of using /amsg to broadcast all over the other channels i am in. Can anyone help me out please? Thanks in advance!

alias mmsg {
var %msg = $2-
tokenize 44 $1
msg $* %msg
}

Put the above in remote (alt+r), then use it as follows:

/mmsg #chan1,#chan2,#chan3,etc message.

Ironically that same command with /msg will work, since most if not all (certainly all I've come across) servers will support multiple targets in PRIVMSG. So /msg #chan1,#chan2,#chan3.. message is ok to use and it being a single command will help avoid you being excess flooded off the server
