I would love to beta test. My office at the University of Washington is considering purchasing this program and we are scheduled to do a webinar tomorrow with new student admits. I would love to do a test run today with my staff with this feature.
I've been using this feature in GoToTraining for over a year now. I'm surprised it's taken so long to make its way to GoToWebinar. In GTT you can set materials to be available before the session in the notification emails, during the session in a materials panel and after the session in a follow up email, or any combination thereof. You can upload a library of materials and links for use among all organizers and sessions. This is good...but overdue.
