When was it first opened quiz
REMEMBER - NO POSTS instead you PM me with your guesses any time up to midnight tonight. If possible, please wait until you've completed all the guesses you want to make to avoid too many PMs and to make my job easier. So no hurry and it doesn't matter when you submit the answers because I'll be judging them solely on who has the most correct - and in the event of two or more being level it will be a tie. I hope this is clear and good luck. Tomorrow I’ll post the names of the top entries.
