lol... more posts about information most of us already knew
aside from my sarcasm. i'd have to second Mokujin, and say it's a wonderful thing to see a useful post from a noob, it being your first post, i salute you.
i also agree that we can call this the Bosi Equation. however, Bosi might want to make it a more flexible one like wolvereness. you all can figure it out, my judgement skills are needed elsewhere.
EDIT: when i said flexible i meant flexible in the mathematical sense... also called "conditional"
