Code:
on *:open:?: {
  msg $nick <message>
}
Here is a complete blocker. It does what I thought you had originally requested, which is to close the pm after they say 3 or 4 lines. Here it is just in case:
Code:
on *:open:?: {  
  set -s %pm.block $nick
} 
on *:text:*:?: {
  if (%pm.block = $nick) {
    inc %lines 1
    if (%lines > 3) {
      close -m $nick
    }
  }
}
It may not be the most efficiant. I didnt put much thought into it. LOL. Then again, that is probably my best anyway. :tongue:
