    If enough people are interested, I will do a short 12 question multiple choice quiz on astronomy at 11 am in chat.

    I am making it multiple choice since variations in terms and wording could make it difficult to judge. By offering standard answers, the first person to post the correct answer wins that round. You can simply type the letter for the answer "a" "b" or "c". This should make it more fair for slow typers.

    Googling is permitted.

    Arguing with the Quiz giver, if you think your answer is correct but not listed, can be done AFTER the quiz is over. If you are right, you will also get a point, then you will be banned for arguing with me. :biggrin:

    Same rules as Zz's quiz. White font, no bold, no chatting.

    11am, whose time? I will be missing it if this is EST - might make it if it's CST. Don't see the chat up yet, so hoping it's CST.
