Meetups are important occasions when Wikimedians (users of Wikipedia and the sister projects) come together face-to-face generally in an informal basis. These have been going on for several years and in a wide range of places across the world. Meetups can have a range of different formats, from "edit-a-thons" focused on a single topic to just opportunities for Wikimedians to meet and chat.
Meetups can be arranged via Meta, the mailing lists, or meetup pages on the individual projects. If you have attended a meetup, you can add a little report here (and link to a longer one, if you're in the mood of writing much).
Also see the page for Wikimedia and MediaWiki related events - presentations at conferences, fairs, arts events etc. This is usually a good occasion to meet other people from the Wikimedia crowd.
Hundreds of Wikimedia meetups have been hosted around the world. If you wish to host a meetup in your area, then consider using the following sets of lessons from others who have hosted meetups in the past.
