Hi Sharyn_Mayne - I only just saw your comment now, so apologies for the delayed response! To get started, please make sure you've joined the Microsoft 365 Champion Program here: https://aka.ms/M365Champions. Once you've joined, head to http://aka.ms/M365ChampionResources to download the calendar series for the community calls, see when the next one is, and access the previous calls. Please note we will be updating the series for 2022 so if you download it now, you'll only see the old calendar invites. Additional resources can be found at Adoption.Microsoft.com: there are adoption journeys laid out by product or by role (Champions being one of the roles). Lastly, if you have any questions, you can post in the Driving Adoption forum and get answers from the community or one of the Microsoft internal folks.
I hope that helps you get started, and we hope to see you in both the forum and our next community call!
