In 2021 this forum has seen quite a bit of activity. Mostly around the time K-9 Mail 5.800 was released. Since then, things have calmed down again. But there’s still a steady stream of people seeking help with setting up accounts in K-9 Mail or finding the right setting to configure the app to their liking.
A few community members have invested a lot of time in answering those support questions. They are the heroes of this community!
