You can tag friends, your page name in your Facebook status and other posts. To tag a name of your page, type the "@" symbol. Then pick the page anme you want to tag from the dropdown menu that appears. If the dropdown menu appears and you don’t want to tag a name, just continue typing your post and the options will disappear. Note that you can also mention page name in comments in a similar way.
