We don’t stop playing because we grow old; we grow old because we stop playing. --George Bernard Shaw
I joined Wikipedia in 2010. What a great concept and opportunity to make contributions that have the potential of helping others. Really, that's what it's all about.
Most of my time so far has been dedicated to the improvement of amusement park, video game, and film articles, although I contribute just about anywhere. I have less time to dedicate than I used to, but try to stay involved as much as I can.
Drop me a line on my talk page if there's anything I can lend a hand with.
