Ed,
not real sure on this one... my gut feeling is that it would be better to start with an empty w3t... that way you don't run the chance of duplicate forum names... however, as I stated before, I don't have a UBB system that I can test these scripts on, so I am, unfortunately, not too much help.

It may be possible for me to help run the scripts if I have ssh/telnet access to the box, but I would have to see when I have time to do that (new house, so every weekend seems to be filled with projects...
