You could send a chan notice...
/notice
#chan hello!
or send a individual private notices by doing the following in a channel edit box...
//var %i = 1 | while ($nick(#,%i)) { if ($v1 == $me) goto skip | .timer 1 %i notice $v1 hello! | :skip | inc %i }
Replace the NOTICE comand with MSG for private messages.
You could turn the above into an alias so they're always available to you...
alias massnotice {
if (($1 !ischan) || ($2 == $null)) return
var %i = 1
while ($nick($1,%i)) {
if ($v1 == $me) goto skip
.timer 1 %i notice $v1 $2-
:skip
inc %i
}
}
alias massmsg {
if (($1 !ischan) || ($2 == $null)) return
var %i = 1
while ($nick($1,%i)) {
if ($v1 == $me) goto skip
.timer 1 %i msg $v1 $2-
:skip
inc %i
}
}
Paste both of those aliases in your script editor (Alt+R)
/massnotice
#chan hello!
/massmsg
#chan hello!

Please keep in mind that most channels don't take kindly to this sort of thing.
