Adding Email for registration

[Pips]

Hi, I've been trying to add email to the registration form.
I'm aware that both the java file and the asp part need to be edited in order to avoid error 404 when trying to display the registration form.
Is there a way someone could help me out?
I'm a bit rusty ^^

Managed to add the field for the email registration, was quite simple, just like any other field (i.e. username)
Now I'm trying to get a page for password recovery by email, any hints?
