I wasn't going to mention this, but screw it.
When you copy and paste a few words with any of them but the last being misspelled, the spell checker doesn't recognize the misspelled words. Try pasting 'thsi dgo is cool' into a forum post or as the title of a new entry. It won't catch that 'this' and 'dog' are misspelled.
I'll be on the lookout for minor shit all week, so hit me up!
