This seems to simple, yet I can't find the info anywhere. I'm looking for a spell checker, that actually allows you to add words to be CHECKED in spell check mode, such as "you're" and "your". As we all know, spell checks will bypass words it recognizes, such as "they're" and "their". The Grammar checks also seem to miss these very commonly misspelled words. I can't begin to tell you how grateful I would be for an answer here.
