I've added a Facebook like button to the website. As mentioned elsewhere, this is just for connecting to the OZgolf.net page on Facebook, which is used for site updates, particularly when the site is down.
I might put it on every page for some early visibility, then shift it to the bottom of the main forum board after some time.
Here's the direct link to the page: https://www.facebook.com/OZgolf.net
Some sites have a lot more integration with Facebook with buttons that enable you to "Like" individual threads (which then show on your Facebook feed) and sign in using your Facebook details, instead of OZgolf's. I don't have plans to do this.
