I know the number. But I won’t say it.
guess a number between 1 and 999,999,999,999

plop it down. i will look here every day and see what's going on. if each post has a different number, with 100% certainly by 1,000,000,000,000 posts someone will get it correctly.
That's a number between 1 and a number having a maximum of 12 digits.
I'll let you know if someone guessed it correctly.
GO!
