As announced a couple of weeks ago, MLC is going to be moving from Classic Hangouts to Google Chat on August 3, 2020. That transition is still on track and will take place on Monday. In order to facilitate the change, we have created a help document titled Google Chat Transition over at KnightHelp.
Links to resources and answers to questions will be posted there as time goes on. That document will also gather resources once the transition has happened.
Thanks and please reach out if you have any questions!
