Awesome! I introduced my employer to some open source self-hosted software recently (Metabase) and now they ask us to look for OSS first when we're looking at existing software solutions.
I posted instructions in the Reddit post about r/cedarrapids shutting down explaining:
how to view this community
how to join lemmy.world and c/cedarrapids
where to find the mobile apps for Lemmy (and how to install their iOS app, since it's in beta and requires downloading via Apple's TestFlight app)
