The home page, news page, match report pages and squad pages now have "Facebook Like" buttons on.
This has the big advantage of getting your visitors to promote your website and your news stories to their friends. In turn, this will drive them to your site and have more people finding out about your club.
Facebook now has 25 million users in the UK. So this seems a very good way of getting others to help promote your club.

Once you click like you can then add a comment and share the link on your profile as shown in pics below. The "like" button is Facebook's new way of doing what used to be called "share".
