Spammer!!! /me kicks Bielie silly like a spam smered between two slices of bread.

Biellie, you can combine those two text events into this:

on $*:text:/(\B[!?]\B|[!.]add)/iS:#:{
  if (!%spam) { inc -u4 %spam
    if ($istok(!add|.add,$regml(1),124)) && (!$2) {
      notice $nick Please provide a line to add!
    }
    elseif ($istok(! ?,$regml(1),32)) { 
      notice $nick $iif($isfile(text.txt),$read(text.txt),text.txt is not found!)
    }
    else {
      notice $nick Added $+(",$2-,") to the list.
      write text.txt $2-
    }
  }
}

Might want to add a check to see if the text.txt exists or not...along with a trigger control so you don't get spammed upon spamming. lol
