There isn't a rule about it, and I don't mind either way. I'm Australian, so I use British spelling. But it's up to you. Use whatever you're used to, or is 'correct' wherever you live. The only thing is that you shouldn't go around 'correcting' someone else's edits if they use American spelling and you use British (or vice versa). Both are equally accepted, and neither is more 'correct' or preferred.
