If you find a typo or have a suggestion, highlight it, and click the little Genius bubble that pops up. (Please highlight more than just one word. Genius gets confused if it's a word or phrase that appears more than once in the story.) The old Orphus system also works. To use it, instead of clicking the Genius bubble, just hit ctrl-enter like before, but Genius might be better because other people can see and comment on what you write.
