--As an attendee, I can visit the event detail page to RSVP for an event:
-I submit my email address by filling in a form. The form has method="POST" and contains an input element with attributes type, id, and name all set to "email".
-If I submit an email address that does not end in "@yale.edu", the form is redisplayed with an error message. (You should accept any valid "@yale.edu" ending: "@Yale.edu", "@yALe.edu", etc.).
-The error messages displayed should be in a ul with class="form-errors" in the same fashion as described in the event creation errors described.
If I submit a valid email address, I see the event detail page again and it shows my email address on there along with the other attendees.
