Nevermind, I finally managed to see my login name in the confirmation mail.
I had not noticed it as it had gone lowercase and expected two
uppercase characters (which simply means I read the confirmation mail
too quickly).

What is surprising though is that when I tried with CamaradeTux
(underscore removed), I was told the user did not exist but
Camarade_Tux existed for the system.
Or this may be not so surprising, I guess the does-user-exist
comparison is not case-sensitive while the real login check is.

Anyway, the problem is solved. ;)
