My question is.... is it possible to change the username and birthday to be viewed while keeping the email invisible?

I would ideally like users to be able to see another members Username and and not their real name. Is there a way to provide and options for the member to choose if they want their real name visible to others?

Birthday should be able to also be selected by the user to either hide or allow others to see it.

Is this possible to set these abilities within the Admin Dashboard?  I have looked within the profile area of both my Admin and the guest user accounts and I cannot find anywhere to make these changes, nor have I been able to locate any place in the Admin dashboard to make the changes for ability to do so.
