Recently, we wanted to create a Slack group for a meetup group in our city. We also wanted to auto-send Slack invites to folks so the admins didn’t have to.
Everyone (especially devs!) love Slack, and we’re on it all the time. One of the best ways we can keep in touch outside of the meetup (meetup.com doesn’t really have a good interface for chatting with group members in between meetups) is to make sure we’re able to communicate and ask questions here between meetups.
