We have the following challenge:
For a client in the event business we want to have a login-page, where the attendees of an event can type in a "password". Depending on the "password" they are redirected to a private page with a gallery and a download link of the images taken on the event.
Ideally the "login" is not user name and password, but a password only to keep it as simple as possible. Much like the password function of WP itself. The challenge is to redirect after the "login" to a "private" page.
Hope it is clear.
