 - `FORCE_PIXELS`: Some screens (mostly mobiles) don't use pixels directly and scale based on the concept of a 'display pixel'. Setting this to `True` tells the device to use actual pixels. Enable with care.
 - `MANGLE_EMAILS`: If enabled, any emails in the `SOCIAL` links will be obfuscated in HTML and have their links generated by Javascript when the page loads.
 - `GLOBAL_KEYWORDS`: A list of strings that will be set as keywords for each page.
+- `FUZZY_DATES`: If `True`, uses [lw-timeago](https://github.com/pR0Ps/lw-timeago) to display fuzzy dates on articles (eg. 'Posted 3 months ago').
 - `SERVER_LESS`: If `True`, `static/css/style.css` will be used as the style (compile it server-side). Otherwise `static/css/style.less` will be compiled client-side with `less.js`.
