FarmVille" posts continual status updates notifying your Facebook friends of your progress within the game. Facebook allows you to hide notices of any Facebook games or applications if you don't want to see updates from them. Hiding these updates blocks them from appearing in your news feed on Facebook. If you've hidden "FarmVille" updates from your news feed, you can easily unhide them by editing your application options.
Instructions:
1) Log in to your Facebook account and click the "Most Recent" link at the top of your news feed twice, until a drop-down menu appears with a list of applications, settings and options.
2) Click "Edit Options" in the drop-down list. A pop-up box appears with options to edit your news feed settings.
3) Scroll the "Hide Posts From" box until you find the Apps section, and then find the "FarmVille" tab under Apps.
4) Click the "X" on the far right of the "FarmVille" row. "FarmVille" immediately disappears from the list, unhiding it from your news feed.
5) Click the blue "Save" button at the bottom of the pop-up box. The box closes.
