You may find yourself wanting to reply to a forum post with just “Thanks!” or “Good job.” or “I agree.” Although we strongly encourage everyone to be supportive, such short posts add little to the discussion, so the Discourse system has a way you can express your support or approval without replying.
Much like on Facebook or Twitter, you can “like” a post by clicking the heart button underneath it. The forum then notifies the poster that you liked their post and shows a number next to the heart that indicates how many people have liked it. It’s a great way to interact in a positive way, even when you don’t have much to say. Remember, you do have to be logged in to “like” a post.
