Here are some tweaks you can make to your Facebook account.
1. If you don't use Facebook's chat function and want to remove the chat sidebar, go to the right-hand bottom of the page, mouse over the little sideways arrow and click "Hide sidebar." Click Chat to re-enable the sidebar.
2. Similarly, to remove the news ticker of your friends' latest actions, go to the upper right-hand side of the page, mouse over the little up arrow, then click "Hide ticker." Click "Show Ticker" to turn it back on.
