[pmwiki-users] A robust user registration module

[Hans]

I am looking for a robust user registration module,
by which wiki users can register by choosing a user name and
password, submit these together with name and email address,
and get a confirmation email sent to them automatically, which
they need to use in order to activate a new registered user account.
It also needs to be easily administered using forms, and to cope
with potential thousands of users.

Any ideas if this can be put together as an add-on for PmWiki?
Has it been done?
