Yes I may have a few little errors in it like the extra || but that is because i use this script and my bot, and i gave myself control over it, and for this script i took myself out.

try this

on *:load: { set %clan $$?=\"What is your clan name?\" | set %clanchan $$?=\"What channel is the clan for?\" }
on *:text:*:{
  if ($chan == %clanchan) {
    if ($2) {

          unset %clangreet [ $+ [ $nick ] ]

Although I didn\'t understand what mountaindew was pointing out, you need to get rid of the or (||) symbols in your if statement under the !addleader command.

what im saying is, u dont need to check if $nick ishop or isop in more than one on text, just put it once, then put the rest under it

Oh yeah, and you should also check to make sure $2 is specified or else you could get error messages. [if ($2) { }]

if u do, ull see theres an extra } at the end

also, instead of doing if ($nick ishop $chan || $nick isop $chan) or if ($nick isop $chan) just do

on *:texT:*:#channel:{
  if ($nick ishop $chan || $nick isop $chan) {
    if ($1 == delfriend) {
      unset...
      msg...
    }
    if ($1 == deletemember) {
      unset...
      msg...
    }
    if ($nick isop $chan) { 
      if ($1 == !addleader) {
        set...
        msg...
      }
      if ($1 == etc...) {
        etc...
      }
    }
  }
}

}

put it back in mirc, click a tab, then go back to remotes, and repaste it so we can see the spacing ;)
