Full summary
"Far and away the best free language-learning app." —The Wall Street Journal "We’ve also tried a few other methods such as book learning and Rosetta Stone, both of which bombed. That’s why I jumped at the chance to try Duolingo. And believe me, it’s addictive." —FluentIn3Months.com Duolingo is changing the way people learn languages. With Duolingo, you learn a language completely free, without ads or hidden charges. You have fun while you learn, leveling up and competing with friends. You have the opportunity to translate real-world texts in the language you are learning, and in doing so, help us translate the Web into other languages. Yeah, it's pretty sweet. Duolingo currently offers courses in Spanish, French, Italian, German, Portuguese, and English, and we are working to bring you many other languages. Stay tuned.	Revert Site lets you get the old Facebook design / layout back (for Biz/Fan Pages and a few other pages too). If you like Revert Site, please Donate to support this project: https://revertsite.com/#donate Revert Site is very quick to install, and very easy to use, it just has a single option, that is turned on by default, so you can just install it and not have to configure anything. However if you wish to temporarily disable Revert Site, you can easily do so by clicking the extension icon, in the browser's extensions toolbar, then un-ticking the "Switch back to the old Facebook design" checkbox. To turn it back on, just re-tick the checkbox. If you can't find the Revert Site (R) button in your extension's toolbar, it may be hidden behind the "Jigsaw puzzle piece" button, so click that and see if its behind there. ** PLEASE NOTE ** Revert Site can only revert Business / Fan Pages, and a few other pages. It can't revert the Newsfeed, Personal Profiles, Events or Group pages. If you find there are any parts of the site that won't work with the Revert option turned on, switch it off while you carry out your tasks, then turn it back on when you have finished to go back to the old site again.
