Post number 476 = the commonly accepted year of the Western Roman Empire's fall. I pwned Rome.
Veni, vidi, vici as they say.

Okay, okay. The mechanic is as follows: Take the last three digits of your post count. Then, if the thousands digit is even, take it as 0. If it's odd, take it as 1. With those 4 digits, you get a year. (For example, if this is your post number 6537, your year would be 0537 = 537. If it were your post number 9976, your year would be 1976.
Now, post something that happened in that year. You can always use
Wikipedia if you don't know.
Have fun?!
