For the MVP we're removing the call to action to sign in and save. Since people are ignoring it, it's not really serving any purpose in the current workflow except to bloat it. This drastically reduces the number of steps in the process. We're flipping the edit summary box and preview around, so that when you make a change and click next you see the edit summary on top. This makes it clearer that your edit hasn't saved, it emphasises the canned edit summaries that users responded positively to in the testing, and makes the preview step feel more optional. We're also going to restyle this page slightly to make it clearer.
