Also a suggestion – look at how the comment editor on GitHub works. I click on any of the icons and it inserts the Markdown for me. I can never remember. And it’s a lot easier to click an I icon than to click underscore text underscore to italicize.
Also I see a character counter at the bottom – is there a limit to the number of characters I can type? I notice it’s red now. Hmm.
Let me try misspelling a word: Missssisssippi. Okay we’re not using the standard HTML editor, or Chrome would have marked that as misspelled.
