I was curious, so I looked into the ubbthreads.php and postlist.php files. Both of them use
$a and
$r variable for the user count. So you could do something like this in your ubbt_registered.tmpl file:
$r {$ubbt_lang['C_ONLINE2']} $a {$ubbt_lang['C_ONLINE4']}That's the same script that's used in the ubbthreads.tmpl file. Since the $ubbt_lang variables are in the generic.php language file that script should work for all pages (at least you'll get the words). Keep in mind that the ubbthreads.php file will generate a value for $r and $a that are for the entire forum, but the postlist.php file will generate a $r and $a that is just for the forum being viewed.
You could add your own custom language entries in the generic.php file and create unique text for your hack
