Solved! Go to Solution.
Good news everyone! GoToMeeting has released a locking feature so that you can keep your broadcasts secure!
Checkout these highlights for all the details: GoToMeeting Blog
Thanks for sticking with us during the development!
The feature is currently available with GoToTraining by closing the registration at specific times, but is not available for GoToMeeting, as it doesn't have an Attendee Registration option. If you want to try out GoToTraining, we offer free trials at https://www.gotomeeting.com/training .
