I have two meetups listed on the meetup.com
site for Apr 4 at 5:30. They both list "Emma" as the location.
That's an accident. Those 2 meetups are the same event. You can RSVP for either of them. I would delete duplicate, except that might communicate to some people that their meetup was cancelled, and I don't want to risk that.
In sum: come to the meetup Apr 4, 5:30pm at Emma! (I think Jeff said he's providing pizza and beverages too!)
