Thanks for the shoutout, Zach! We had a google calendar that members could subscribe to where the Location was the Slack post from Tightknit. Another suggestion is doing a weekly Slack announcement with a list of that week's events.
Directing members to the Tightknit app to see events in there is great, but it's nice to have other reminders or ways of integrating into their usual habits (like looking at google calendar, etc.)
