[web2py] Re: email/password login only: How to change email to lower case at the register page and store as a lower case to the database.

[thstart]

I am using email/password as a login.
After login I want to have an option
for the user to be able to change his email
used as a login.

say the user logs in with myem...@gmail.com/****
after log in he clicks on a button (change your email),
a form is present where he enters his new email
as newem...@gmail.com. 

He logs out, and now he can login with 
newem...@gmail.com/****

e.g. auth_user.email used to be myem...@gmail.com,
after the change to be newem...@gmail.com
