*Make sure that during and after the event you are keeping a tally of the attendance. You need to know what you are doing right and doing wrong! If you see the cinema pop-up class got half the numbers of the computer science pop-up class, the hard data is necessary to figure that out.
*To further accurately get a picture of how your event did, set up a way to get anonymous feedback. You may think the event went splendidly, but if 75% of attendees were unhappy, it's best to see why. It may be stinging criticism (especially after all that work!) but if you want to learn from your mistakes- or your victories- this is how you do it.
*Take pictures so you can show off your event to others later, and spread the word visually of the awesome event.
