Can you tell us more about what kind of support Substack is offering? Like do you have a database of Substack writers by geography that enables you to send an invitation out to everyone in a particular area (DC in my case) who might be interested? Or do writers need to find one another independently?

Another way to do it would be to ask everyone who is interested in a meetup to fill out a form, and then you could provide those email addresses to one or more of the people who volunteered to host so they can discuss the best time and location.

Anyway like others I'm finding this process confusing. I would like to attend a meetup and am open to hosting but I need to better understand what I'd be signing up for.
