I used Batch Create to add users from my old website (www.thedigitalartist.com) to my new one (www.thedigitalartist3.com). The txt file was very carefully edited, and I didn't get any error messages while the queue was processing.
However, it only created about 1/3 of the users that were in the file, and, unfortunately, didn't create any of them as BP users.
The main problem is that it created more than 7000 tables in my database. Any thoughts on how I might undo this without scrapping the site and starting again?
