Quick Survey #1: Do you use "spelled" or "spelt"?

Both are considered acceptable forms of the past tense of “spell.” The usage of “spelt” for the past tense of “spell” is dying out, even in British English. It is used relatively rarely in American English, where spelt usually refers to a type of grain. So, which one do you tend to use? Or do you use them both equally?

Optionally, you can tell us your general geographic location, so that we have a good idea of what version of English is used in your area.

I live in the southern US and normally use spelt, although I sometimes also use spelled. I was inspired to ask this question when I realized that my Google Chrome spellchecker doesn’t recognize “spelt” as a real word (not even as the grain).
