Thanks for the response mate, I've so far been using do=update&userid=X - I took a peek at the script and realised it could be done. It seems only around a 3rd of users haven't been updated so I'm going through The Shoutbox page by page and checking the userid's of users not assigned and showing as '0' and then updating them. My Shoutbox is 750 pages... I'm 200 pages in lol.
