If you’re looking to talk with other users on these forums about TestFlight builds of OmniFocus 4, this is the right place!
That said, this isn’t the only place to talk with other folks about the TestFlight, or even the most popular one: you might be interested in joining the thousand-plus throng in our #omnifocus-4 channel on Slack.
I have been using OF 4 in Test Flights for months and would love to be part of the Slack channel. I have entered my email to receive an invitation to Slack probably 20 times and I never get an email in my inbox or junk folder. Is there anything else I can do to be part of the Slack channel?
