Sort members by login method

[Kjell Iver Johansen]

Is it possible to see or check how many members that need to change log-in method when change is coming from using log-in name to e-mail adress?

This is not recorded if a user logged in via display name or email address. I would recommend placing a warning to all visitors at some point that the change is coming though. We will provide some suggestions and further tools once we get closer to V5
