Code:
on ^*:QUIT:{
  if ($nick == $me) { goto end }
  set %quitmessage $1-
  if Ping timeout isin %quitmessage { set %quitmessage Ping timeout }
  if Connection reset by peer isin %quitmessage { set %quitmessage Connection reset by peer }
  set %quitchan $chan
  %quit.1 = 1 
  :quits
  if ($nick ison $chan(%quit.1)) { 
    set %quit.echo $chan(%quit.1) 
    themequit
    inc %quit.1
    goto quits 
  }
  elseif ($chan(%quit.1) != $null) { inc %quit.1
  goto quits }
  halt
  else { goto naiquit }
  :naiquit
  halt
  :end
}
alias themequit {
  if ($window(@events) == $null) window @events 60 100 600 200
  if %quitmessage == $null { set %quitmessage no reason }
  echo @events $chan(%quit.1) $nick ( $+ $address $+ ) Quit ( $+ %quitmessage $+ ) | haltdef
}

This whould work to echo the quit events to @events .. and yeah, i mixed them up smirk so add haltdef in the end of the other events would hide the messages in the channel..
