I have a modified rebuild.php for sites with large numbers of users. What was happening on our system was that the update would take too long and crash, leaving a mess on the floor. The rebuild has been re-written so that it creates a 'work' DB with all the users that need processing, it then reloads itself in update mode and processes 250 accounts at a time until all updates have been completed. Not after huge amounts of $$$ but if you want it ask, make an offer Larry
I'm intersted because it seems that this system cannot rebuld any more than 76K in member records. This is preventing my launch. PM me and we'll talk price. Thanks!
