I didn't test it but I think this is what you wanted(I added multinet/channel support aswell):
Code:
on *:DICONNECT:{ unset $+(%,wait:,$cid,:*) }

on @*:JOIN:#:{
  set $nwait($chan).noop $nwait($chan) $nick
  $+(.timerWait:,$cid,:,$chan) 1 5 nWaitAdminMsg $chan
}

on !*:NICK:{
  var %x = 1, %c, %n = /(?<=^| )\Q $+ $replacecs($nick,\E,\E\\E\Q) $+ \E(?= |$)/
  while ($comchan($nick,%x)) {
    %c = $v1
    set $nwait(%c).noop $regsubex($nwait(%c),%n,$newnick)
    inc %x
  }
}

on @*:TEXT:!next:#:{
  var %n = $nwait(#)
  while ($$gettok(%n,1,32) !isreg #) %n = $gettok(%n,2-,32)
  mode # +v $gettok(%n,1,32)
  set $nwait(#).noop $gettok(%n,2-,32)
}

alias nWait {
  if ($prop == noop) { return $($+(%,wait:,$cid,:,$1),2) }
  return $+(%,wait:,$cid,:,$1)
}

alias nWaitAdminMsg {
  if ($me !isop $1) { unset $nwait($1).noop }
  else {
    var %n = $nwait($1), %r, %x = 1
    while ($gettok(%n,%x,32)) {
     if ($v1 ison $1) { %r = %r $v1 }
     inc %x
    }
    if (!%r) { unset $nwait($1).noop }
    else {
      set $nwait($1).noop %r
      var %x = 1, %a
      while ($ulist(*,admin,%x)) { %a = $addtok(%a,$v1,44) | inc %x }
      if (%a) {
        msg %a The following users are waiting for help: %r
      }
    }
  }
}
