How I can make users register by name and password only without e-mail? I searched a lot but all what I found for old wordpress version Can anyone help me in this?
WordPress registration process is based on the use of email. You can create your own registration page, and use fake random email just to fill the required email field, but you need to custom code registration process up to a point.
How will you reach your users, if you have no way to contact them?
