FBML provides the code to include a little share button, like the ones you see on the bottom right of the wall, on your customized fan or business page.
When you are on any tab on a fan page other than the wall, there isn’t a share button, so it’s useful to be able to add one so that visitors can share the page with their friends or even post your page to their own wall.
And this little bit of FBML is super easy to use.
