1derful is correct. Any place God's name is written, it is supposed to be buried and not destroyed. This, IMO, mainly applies to when it is written in Hebrew. Most of the time, God's name in Hebrew is written as "his name". Interstingly, there is no correct pronunciation of God's actual name in hebrew - it is a yud,chey, vhav, hay (SP, i don't know how to spell the hebrew letters in english...). So Yahweh is not God's name - the reason nobody knows how to pronounce God's name in Hebrew is because it was written without any vowels, and only the high priest from the ancient temple knew it, and recited it only once a year, drowned out by the other priests in the temple. I've seen Orthodox Jews write God as G-d as well, though.
