As promised... in Site Updates

My hope is that most users, now that they've had a chance to get used to the editor changes, either enjoy the new style or are indifferent to it. However, I know that some people still think it's horrid (and at least one user isn't seeing the text at all via phone). So I like to provide options.

There's a new Editor Style section under Settings (directly below the Theme selection). You have a couple of choices, the default being "Modern", and the old style as "Classic". If you like the old school, maybe Classic is more your thing. :)
