There isn't, but you could add a plugin to sort them. Using hook showthread_whoread_list, you could use code something like this:

PHP Code:

if (!function_exists('wrt_compare_username'))
{
   function wrt_compare_username($u1, $u2) { return strcmp($u1['username'], $u2['username']); }
}

uasort($wrtlist, 'wrt_compare_username'); 


(but I haven't tested it at all).
