yeah i would go with what EL told you to do.. maybe somthing like this to get you started
on @*:TEXT:!assist:#: {
if (!$($+(%,assist,$chan,$nick),2)) {
msg $chan Please wait, Finding an available Op.
onotice $chan You are needed in $chan By user $+($nick,$chr(46))
set -u300 $+(%,assist,$chan,$nick) on
}
}
