i upload user via csv and fill these field ( username, passwords. firstname, lastname and email ).
i really dont want to using email based authentication.
i won't
necessarily know the: first name , last name and email of each user at
upload time. So i was going to add a default e.g. firstname1,lastname1, firstname1@nomail.com .
i'd like that the user can change ( force users ) these fields when they first login but after that it is locked.
please somebody help me.
thanks in advance for any help.
