Please don't request email address when authorizing using github auth. This invariably leads to spam, either intentionally, or accidentally when services don't guard their database / email sending. Instead make this optional and if not entered prompt me to provide an email address once signed up (and do the right email confirmation dance as needed).

Then ask for an email address for that purpose... in your app... for your app...
