Allow user to change their email with option to show/hide it
A user should be able to change their email address after registering, as well as have the option to show/hide the email from the public. This would probably be the first feature of a user profile/preferences page. Other profile items could include photos and other information user's would want to share about themselves.
Good idea. It would also be nice to cookie a session so that when you're signed in to the dinner site and navigate over here, you don't have to sign in again.
