What is the difference between a closed thread and a banished thread? Does it depend on a mod's mood? Does one have more honor/shame than another? Are banished threads extreme bad examples to all, like a head on a stake?
I would *guess* that leaving it blank gets you converted to a zero or something, and since there ISN'T a zero, it carries you back one. Maybe we'll "fix" that later....or maybe everyone else will just correctly input their birthday.
