>Oh yeah...color/colour, neighbor/neighbour, etc. Love how the spellchecker here on the UT says that our words are "wrong" :)

If "spellchecker" is in reference to other members telling what you wrote is wrong then I would say it is a new variant of spell checker. Other than that, I do not have any spell checker in place. If there is something like that, it comes directly from the browser you are using.
