Emi and I never got "another prize".
Excalibur, I said "at least a day in advance". I'm talking about events like this one, not "big events". I said "at least" because it should be at least one day at the minimum.
Planning events like this a week in advance is silly. Nobody would show up because it's not a HUGE MEGA event. That is why you schedule smaller events a day in advance, and bigger events a week in advance.
