This project has been pernemently placed onto the backburner.
The script works fine, however I simply do not feel that the majority of users are ready to use it. It is a VERY powerful tool, and like my username rewrite script which will forever be public beta, it has the destructive potential to cause your UBB to melt down into green goo, never to recover again.
Not that the hack would be used for very long - UBB6 uses a different method of storing forum information that allows forum deletion. It's the only known feature of UBB6 so far... Just a matter of waiting for it, guys.
