It seems to me quite complicated. For me the account manager, I don't
care, but for the user this is a big issue. I'm pretty sure that most
users won't make the difference between Drupal account, demexp account,
account validation, etc.
I fully agree with you.
2. At step (2), when the user receives his password, we should *not*
provide a way to change the password. The login message should make
clear that this is only the *Drupal* login. Moreover, in English we
call the project "the democratic experience" (in lower case). So I
propose following message template:
"""
Toto,
Thank you for registering at the Drupal interface of the democratic
experience. You may now log in to http://demexp.ouvaton.org/user using
the following username and password:
username: Toto
password: ghjgqsjgds7676G
-- The democratic experience team
"""
I agree but I would not mention the word "Drupal" (remember we're
targetting the average user), I would use "web interface" instead.
