Just  wondering how I play the weekly quiz on thursdays? Do I have to be in the chat room to play? Is there somewhere else I can find it posted? What kind of quiz is it?

Also how late do most people stay up chatting...I live in Japan  so if I`m online in the morning say 8am it would be midnight in good old Blighty.no one seems to be in the chat room then....which is a shame....any info would be appreciated.Thanks. Glawen
