Code:
  
alias highset {
  if ($nick($active,0) > %highestPeeps) {
    /set %highestPeeps $nick($active,0) | /set %highestPeepTime $fulldate
  }

%highestPeeps 30
%highestPeepTime Wed Feb 18 21:04:52 2004

$active refers to the channel inwhich you type /highset
when adding a /something to a remote file you need to code it as
alias whatever { which is = to /whatever
if you want you can add a variable to return the channel which you were in such as
set %highpeepschannel $active
hope that helps smile
