A small piece of advice for others: the free version of the User Meta plugin has very little functionality. If you were like me, and looking to create editable metadata fields for users in the backend, and then use the awesome importer that Ulrich has written, his plugin + Register Plus Redux is a great combination.
To be clear, the User Meta plugin does everything it says, it will create those metadata fields in the database, which you can then use as fields for importing users, but, as far as I can tell (please correct me if I am wrong), you are not able to view or edit them from the admin without the User Meta pro version.
Also, Register Plus Redux was recently taken down due to a security hole found in its code, so User Meta Pro might be the only way to go for now.
