On my original board there are many users, but these were created with just usernames and passwords. Because of the type of system we were not allowed to get information like email address. Now when I import my users I have a problem as these are all assigned to "guest" and no real username. Also my users won't be able to login anymore as they don't have accounts.
What can I do to create these user a/c's and have the ability for them to log in on the new vBulletin ?
