Hi Hannah! Thanks for reaching out. Medium is simply a publishing platform — a place for us to publish blogs and articles to social media, and it has nothing to do with our Meetup site. So nothing to worry about there.
As far as #MeetupAmerica goes, we’re calling all organizers to use that hashtag in the names of their Meetup events if they want to participate, so that it’s easier to categorize these Meetups on our site and makes it easier for people to find them.
So if you’re interested in participating, simply create an event and use #MeetupAmerica in the title of the event. The type of the event is up to you, whether you want it to be a political discussion or just a regular Meetup. The goal for the #MeetupAmerica week is to get organizers to utilize the Meetup platform for it’s primary purpose: to bring people together.
Let us know if we can provide any more information!
