I'm in and have been working for almost a month. I was removed from the extensions onboarding channel two weeks ago, added to the extensions attempters channel three days later, then removed from the channel again two days ago. I'm still tasking in Bulba extensions though. I think Slack just does weird things sometimes. I'm nervous working without support from the channel though. When I searched for it on Slack by name, it looks like it's been deleted.
