After a 3-month follow up, 60% to 100% of contest participants were retained as active editors, with an average of 83%. Six months later, 60% to 80% of contest participants were retained as active editors, with an average of 79% actively editing six months later. Further research is needed, based on seasonal editing changes (i.e. Wikipedia gets edited less in the summer, versus the winter), but early research shows fewer participants are actively editing six months after the contest. We need to research more to learn if contests do motivate editors to produce more for a specific time period, and then they return to their normal editing activities, or, if contests lead to a declined rate of editing post-contest.
