When you first log in to Facebook, a news feed displays that shows your friends' statuses and activity updates, including FarmVille updates that relate to events in the game. Facebook gives you various options for managing the content that appears on the news feed, and allows you to hide news feed updates from specific applications, pages and people. If you previously hid FarmVille, you can remove it from the hidden items list to view its activity posts again.
Instructions:
1)Log in to Facebook to display your news feed. If you're already logged in and on another page, click "News Feed" under "Favorites" in Facebook's left panel.
2)Click "Edit Options" at the bottom of the news feed.
3)Click the "X" to the right of FarmVille's entry in the "Hide Posts From" section of the settings window. Click "Save" to stop hiding FarmVille in your news feed.
Tips & Warnings
If you blocked and hid FarmVille, you need to unblock the app to see its posts again. Go to the "Privacy Settings" page, then click "Manage Blocking" near the bottom of the page. Click "Unblock" next to FarmVille's name at the bottom section of the page.
