QR codes and invite expiry
Print the QR for the breakroom; emailed invites die on their own clock.
QR code: every join link has one — press QR code to view and download a printable PNG (the access code is shown alongside). Perfect for onboarding decks and breakroom posters.
Invite expiry: when you email invitations, each emailed link carries its own expiry (you choose: 24 hours to 30 days). An expired personal invite politely refuses — but the main link keeps working until the close date you set.
