This new modification allows the admin to add one or more buttons to the top of a topic's view to allow users to link the topic in social networking sites. Sites UMO has added are: Facebook, MySpace, Twitter, Yahoo and Google

What this means is at the top of a post you will see buttons for the listed social networking sites. You can click on one of them and it will share the link to the post on your networking site. Doing so will help UMO grow and you will be helping to spread the word.
