These can vary, based on your event. We often:
- Ask attendees to share their successes. Find a few people (perhaps 5) to stand up and speak for a minute or two about what they accomplished during the day.
- Get attendees to fill out your exit survey. Typically, you should plan your exit survey in advance of the event. At the wrap-up, you can use a projector and project a URL of the exit survey (preferably shortened with a meaningful name, using a service like http://bit.ly/ or http://smarturl.it/ ).
- Thank people. Sponsors! Staff! And don't forget the attendees - they are there! You are glad they are there.
- Hand out tokens of appreciation, if you can. Attendees often love to receive T-shirts, books, stickers.
- Follow up:
- Tell attendees to expect a follow up email and an invitation to join the alumni list (if you have an alumni list) and/or the general OpenHatch mailing list.
- Let them know about follow up events. If this is obvious -- like inviting people to a "project night" after an introductory workshop -- great! Make sure to share that recommendation, and do so with high clarity. Perhaps put the URL on a projector, and give people 90 seconds to check their calendars and sign up for it. If the follow-up methods are less obvious, think harder: for an open source outreach event, are there conferences nearby that are coming up? Is there a programming user group that welcomes newcomers that might be a good fit? Mention them, because attendees new to the community are likely to have never heard about them.
- Encourage attendees to keep hanging out on IRC, keep doing training missions and to keep working on the bugs from our bug tracker.
- Remind them about programs like GSoC and GNOME outreach.
