Okay, This is a huge pet peeve of mine. Don't change spellings based on dialect. If you're from a Commonwealth country and see the word, "color". Don't change it to "colour". On the same note, if you're American don't change "tyres" to "tires". Seriously, it's not cool. I will not tolerate a pissing match about which written dialect of English is correct. They both are, grow up. Standard operating procedure on rules violations will apply to this.
