How to Sign up for Reforged Beta?

I’m aware they announced there would be a beta sometime early 2019. Just wondering how we can possibly sign up for the reforged beta. Also, if there is a possible date that the beta is going to be released.

Thanks

But ultimately go to your account settings and make sure Warcraft is checked in beta preference.
