Users are not advised upon creating an account at MediaZilla that their email
address will become their username and be visible to anyone on all MediaZilla
bug reports voted on or created by that user.
At the least, the create a new account page should advise users of the lack of
email address privacy. (Personally, I assumed that email would be required to
confirm that I was a real live person, and then allow me to create an account,
not for becoming my username.)
