Quick summary
Why switch from Sesh to Atomcal?
Most calendar bots stop at Discord posts and a sync toggle. Atomcal is a calendar with extensions — Discovery gets your community found outside Discord, Magic Invites fills nights from real attendance history, and Member Analytics shows who’s actually showing up.
