Hey Colin... you must have never ran a search on Google for a spell check engine!! I offer the following~only 310 results.
Hope ya find one that works~ I don't need one for spelling errors, I need one to translate my typonese, so the rest of the world can decipher it. I pride myself in being a good speller... it is those danged typos get me half the time... did I say half? Who am I kidding?
