This tells me four things about spellcheck:
1) It obviously hasn't been updated in the last decade. It doesn't recognize Ikea, Craigslist, Paypal, or hyperdrive, words that every American today knows and uses on a nearly daily basis. Especially hyperdrive.
2) Its database is extremely low on useful expletives. For Shame, Google, for shame.
3) Really the only word I don't know how to spell is
4) I just coined at least three words! I am a genius!
In conclusion, please feel free to consult me any time in the future that the English language just isn't doing enough for you. Except in cases of actual misspellings. Then I am NOT your girl.
