A summary of how you tried to research your question. Simply saying that you used Google and Wikipedia isn't enough. What are some of the search terms you tried? What articles did you read?I've been letting these posts through because I don't want to be a hard ass, but the rule was made to address problems in the community, and if no one follows it those problems will come back.
If you haven't posted in a while, please read the user info before doing so. If you don't, I might reject your post, which wastes both your time and mine.
