Originally from bcaviness:

I've seen this done on other forum sites that I've been a part of, and I wanted to run it by you guys and see if you were interested in trying it for this year. Here's the way it works, someone, we can appoint later, comes up with a list that posters would need to take a picture/video of his/herself doing/seeing to gain points.

DLO members form teams (let's say teams of 10), and you have three weeks to score the highest number of points.

Discuss this idea here.
