Use Email As Username

I have used membership pro for a number of years, in the past users registered using a username.
I would like to enable the "Use Email As Username" for new users signing up.

If I enable "Use Email As Username" will my older users still be able to sign-in using their username?
I have a lot of users that log-in using the autosaved info.

Thank you.

Hi Kora

Yes. The system will still allow users to login using their old username, don't worry
