Guests and visitors are now able to "Like" or "Dislike" posts. Every post now has a thumbs up and a thumbs down icon (located on the top right-hand side of the post). Click on the "thumbs up" icon to like a post and click on the "thumbs down" icon if you dislike a post. Keep in mind that you cannot like or dislike your own post.

Topic Tags: adds an efficient modern and simple to use topic tag system. As a member, when you start a new topic, you'll be able to add tags to your topic that can easily be searched. You can add new tags or use ones that are auto-suggested as you type. When you start a new topic, the tags options will be available under the "Subject:" line, as shown in the screenshot below. Have fun!
