i don't know if such a hack exists, but it wouldn't be hard to implement it

you have to add one field to usertable
edit member.php and one user-cp template to allow a user to change the value
and one really small change to showthread.php

lets say you add the field postorder to your usertable, you have to change this in showthread.php:

PHP Code:

// oldest first or newest first
if ($postorder==0) {
  $postorder="";
} else {
  $postorder="DESC";
} 


into this:

PHP Code:

// oldest first or newest first
if ($bbuserinfo[postorder]==0) {
  $postorder="";
} else {
  $postorder="DESC";
}
