+ in front of the UserLevel means that it will be triggered only for that level and not higher, if u want it for level and higher use:
on 1:deop:#:{
if ($opnick == $me) {
chanserv op $chan $me
mode $chan -o $nick
}
}
btw, u can replace 1 with * so it will be for everybody(even for users that their level is a WORD)
