We've added a Recommend button to each post on Chowhound. If you see something useful or interesting, you can click to recommend it. You can recommend as many posts as you want, excluding your own posts. Click on the recommend button a second time to remove your recommendation.
You can hover over the number (or click, on mobile) to see which users have recommended a post. Recommends are listed in reverse chronological order (the user who recommended a post most recently will appear at the top).
Like with all new releases, we'll be monitoring how the recommend button gets used, and we'll also be gradually adding features to it. If you notice any bugs with the recommend feature, feel free to report them on Site Talk. See our FAQ on Reporting and Solving Technical Problems: http://chowhound.chow.com/topics/877664
