If you don't want to use slack, for privacy reasons, join the Boolberry channel on Spider Oak's Semaphore. The team ID is: S6R4Z7I6Z6QUCCXXT7SOGU25I3UE7IIZLEAAQYUWILOA3QAYRKUQ
You also don't need to join with your email address.
Greetings,
That's correct, you don't need an e-mail address to sign up or even a password. Semaphor generates a recovery phrase that is used to recover your account. Moreover, unlike Slack, Semaphor doesn't log user IP addresses.
