The MIX07 team posted this message Tuesday evening:
Many of the session recordings from yesterday are now posted! Visit sessions.visitmix.com to browse the
thelist. Sessions will continue to be posted as the become available from our production team. We've provided an RSS feed to alert you when they are added and we'll also highlight here some of our favorites as well.
The session videos are no longer locked down. The easiest way to view them is to subscribe to the RSS feed. Double-clicking an item in the feed opens the sessions.visitmix.com with the code for the event you clicked in the search box.
However, the team forgot to mention that the videos have an ACL that requires a username and password. The Registration page says nothing about how to obtain a username and password.
