I rolled out GSuite for my last district and have become a defacto professional development coordinator for all things Google along with a colleague of mine.
In my not tech life, I enjoy cooking, travel, and reading SciFi.
Maybe instead of a discussion board you could try creating a Google Site. The website could act as a hub for all the great tech you and your teachers are finding. You can link how-to videos that you find or create, curate the space into different tabs or subpages, etc.
Just a thought!
