Get GroupApp

GroupApp is in a private beta. While sign-up is limited to authorised addresses, an install invitation comes from the person who invited you, for the email address they authorised; this page does not by itself authorise a new account. Once sign-up opens more widely, you can install the app here and create an account without that prior authorisation.

To join a group, ask someone in it for the group’s code. An admin may still need to approve your request to join.
