I use raw 366 to echo the nicklist to the channel but when there is a certain amount of users i don't want my screen to get flooded and i would like it turned off. How do i halt this if the channel has lets say, 100 or more users

raw 366:*:{
set %sync $readini data.ini joinsync $2
joinsync $2
}

Simply add an if statement to check if ($nick($2,0) < 100) before performing the commands
