Using WP 2.9.2 with bbPress 1.02
We just converted from phpBB to bbpress, and in the import, duplicated a number of users (email addresses). The result is that each of these users can login and view, but even after login, when they go to post, it says "You must login to post".
How can I find all the duplicate email addresses and delete them? Other than the obvious one-by-one approach.
