is it possible to see how many/who has signed up for open beta?

I have set up my app and prepared open beta using the Android Developer Console, but now I want to know how many have signed up for the beta. Is it possible to:

• See how many signed up for open beta?
• See who (by email) signed up for open beta?

I tried a google search, but all that appeared was information about alpha/beta testing and how to use it. There was nothing on seeing who/how many signed up for it.

Is this possible?

Yes, you can see how many users have enrolled to be beta testers. You need to go under the "Beta testing" tab in the "APK" section. See screenshot:

You can't see the user email though.
