like the total number of bitcoins? block processing rate could generate multiple choice scenarios? um what is a hash? number of bitcoins in each new block? current mtgox price? the parts of a transaction? the parts of a block? calculate a hash tree?
Oh fuck that, I can't answer most these questions lol
I think a politeness check is more in order. People will learn about Bitcoin as they are on the forums, they will not learn to be nice people though.
