Event Registration Questions

Starting with the registration field.

You see a different registration page with a Login and Email Address because your account is set to not default to emails as the login. This seems to be a change the may have come in one of the more recent patches, as I don't recall that setting affecting Events before. If the account is changed to default to the Email Address as the user login ID, then it changes this field to the image on the right. This setting can be found at Administration > Users and Groups > Edit Login and Password Policies. It is the first option under Login Policy.

Events Reports

For the reports not showing emails, what report are you looking at? If I click on the Number Registered or Number Attended report on the Summary Reports page I see a list of names and emails. Also, if I select to Download Report Data from the User Information Report on the same page, I get a CSV file with the information from the registrants. The Login field should be their email unless they used the Login option from the above explanation. When looking at the Registration reports page, i see the Email address field in the graph, but it only indicates the number of registrations that provided an email, not the specific emails. By Answers doesn't show the responses to the default 4 questions, but will show any additional responses desired for the registration.

Hope that helps clarify what is happening and why.
