Multiple people have posted on the forum asking for a like button. There are like plugins for this forum, some of which connect to Facebook and some that don't, and that is fine and good. However when I set up this site I took advantage of a more powerful addon called YAGA, short for: Yet Another Gaming Application. This addon allows users to respond to posts in any manner we deem valid and comes with a set of reactions for which I didn't even feel the need to expand on.
How do you use this system? Its simple. Hover your cursor over a post that isn't yours and the reactions appear underneath, like so:
Next to the quote option you can see: Promote, Insightful, Awesome, LOL, WTF, and Spam. When you click one of these you'll be recorded as responding to the post that way. Additionally, a small icon will appear under the post noting your reaction.
Part of the reason I say this is more powerful is that the system offers a way to read the forum based on reactions. You can find this on the left sidebar, by clicking Best Of... under Categories. This takes you to a set of pages that let you see the most promoted, most insightful, etc posts as recorded by the reaction system,
