It is easy...You answer an unknown number of questions in a category and get an unknown number of best answers in a few weeks and one Monday morning you will have that crown. You cannot get it in P&S or Jokes and Riddles. Despite Yahoo claiming it means someone has knowledge in a category that is inaccurate as it is not based on quality of Answers (best answers received are not always the best ones) but whatever number meets the formula requirements.
No one knows the formula, how many answers it takes or what % of best answers is needed. You can lose it too if your contributions drop below what is required.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
