Dislike button WPforo

Is there a basic like/dislike button to use with WPforo? I tried the like dislike plugin by WP Happy Coders and it didn’t work. It didn’t display. Is there an option that might be free? If not, I’d appreciate any suggestions for plugins. Also, is there something maybe already built in for WPforo? We use it a forum and would like to have a Dislike button at the bottom of a post. We already have the Like button but would like to add the additional Dislike button. Thanks for your assistance.
