Are there any active groups on Facebook for Madison, WI?
The local BP meetup group (free) has a fairly active Slack presence and meets every other week on Weds nights, but I'm not aware of a corresponding FB group for the same. I believe there is a requirement that you attend at least one meetup (currently via Zoom) to introduce yourself before the group facilitators grant access to the Slack group. DM @Jack Medford if interested in learning more.
The local REIA (paid membership) has a somewhat inactive private FB group, but fairly active meeting attendance and community.
