User blog:Gator Von/Guess what happened in this date (plus some other questions)

Today is the 11th of septemberc(in my timezone), exactly 18 years ago on this day, something happened. Can you guess what?

Maybe some of you are able to answer my other questions, about PWSC (Polandball Wiki Song Contest).
 * 1) First, as far as i know you need to submit a song to participate, but how exactly?
 * 2) Then how i vote ?

Hope someone will answer
