I have made a Ringo Quiz with the ProProfs website.
I tried to gather 10 questions for hard-core fans, but I suppose some people will find it super easy
Anyway, you can take the test
here. Enjoy!
Don't forget to post your results here.
And maybe think about doing more quizzes to share with us
PS - The source for the questions was mainly the Ringo Trivia Thread and Wikipedia, altough I lurked through some japanese websites and frecklegirl's Nostalgic Lavender. Don't cheat!
