Yes, the hack should enable the administrator to add 2.000 users or more at once. Usernames, Mailadresses and Passwords are to be in a CSV-file (excel-file), which we would generate automatically.
If this is too complicated, the hack could also do the following: Generate 2.000 (or more) new users with a name, given by the admin, starting at a given number, giving them a generic mail-adress with a given domain. (i.e.: user0001 - user2000 with
user0001@domain.com -
user2000@domain.com). But it should also end with a downloadable CSV-file, which contains username and password.
Of course we could sit down and insert 2.000 users by hand. But that's a bunch of work. And if could be easier...
