Near the top right of all on-topic (and other search engine indexed forums) threads will now be a facebook linked "like" button... if you see a funny or cool thread and you're a facebook member hit the "Like" button and it will auto post a link on your wall under 'recent activity' so you can share JUOT with your friends. This isn't available for off-topic posts because people would get a 'not logged in' error since OT isn't viewable to guests, but On Topic and OT Light is. Forums where users regularly use this have seen serious increases in visitors and a small fraction of them may become new members.
