hehe nm, i got it:
$count($4-,N) how many are in channel
$count($4-,@) how many are ops
$count($4-,%) how many are half ops
$count($4-,+) how many are voices
and for normal users i would do:
set %users $count($4-,N)
set %ops $count($4-,@)
set %half $count($4-,%)
set %voice $count($4-,+)
set %temp $calc(%ops + %half + %voice)
set %normal $calc(%users - %temp)
echo %normal
that would work right?
