Check out the web page on the Episcopal Church Foundation's Vital Practices website.
There's a collection of resources related to Episcopal Church governance, structure, and polity as well as tips for reporting on General Convention. On down the page is a list of links.
The orientation videos have been posted on the General Convention website. You can find that page here: https://www.generalconvention.org/orientation-materials-gc2018/. Or just click on the Orientation Materials in the GC menu on our front page. You can direct people to that site if they want to watch the videos remotely.
Here is a link to all the downloadable videos (in the intended viewing order).
We recommend Provincial Coordinators use this link to download the content if they are going to play it during their in-person Synod meetings (or otherwise want to view it offline).
