Chance meetings are wonderful. But when you have an opportunity as rare as this one, why fall back upon chance when you can facilitate? When you can do more, you should.

For instance, what if the color coding was expanded upon and added to the invite application? Each individual could place themselves in the category that describes them the best and then know at the time of the event the people they should be talking to rather than wandering around hoping their next chance meeting is the one that makes the difference.
