*sigh* That is annoying. Whenever I read a fic with British/Canadian/everywhere-except-the-US spellings, I'm thrilled. I also have to admit to downloading some of my favorite fics and using the find and replace feature in Word to change 'center' to 'centre', 'mom' to 'mum', etc. (simply for ease of reading.) Even though I'm American, I read mostly HP fic and I tend to expect British English.
