If you want to let your visitors easily share your content on social networks or online bookmarking services, you can insert a toolbar with buttons for sharing on Facebook, Twitter, Myspace, and other popular services.
To add the Share on Social Media toolbar to a webpage:
Go to the Modules tab, select Social Sharing, and drag the module to the page.
Select the appearance of the toolbar.
If you want to modify the list of social networks and sharing services shown on the toolbar, place the mouse pointer over the icon [+] and click the More link.
The changes you make to the list of services will be visible after you publish the site.
Note: When someone shares your content on Twitter by using the Tweet button, the counter of tweets is not increased immediately. It can take several hours for the counter to update.
To remove the Social Media toolbar:
Place the mouse pointer over the toolbar and click Remove.
