Started a small Non-Profit, should I mention it in App?

<p>In about 9th grade, I started a very small non-profit organization that dealt with providing new media space, especially over the internet, to worthy causes.
The month to month turnover was usually high $X,XXX to low $XX,XXX </p>

<p>I'm considering including something about this in my application, because it did take up a significant amount of my time and I figure that this would be an EC that would stand out, and that not many other people would have. </p>

<p>Do you have any suggestions as to whether or not I should include this, and if so, can you suggest an appropriate way to do so? I don't want to come across as boastful. Also, I stopped working on it several months ago due to external circumstances. How do I describe these without sounding negative, or should I only give these a cursory mention?</p>

<p>mention it and then write one of your essays about it</p>
