Facebook's Timeline feature will become permanent for all users starting today. Facebook will start opening up the new profile today, and everyone will be updated to it automaically within a few weeks. Once your profile is updated, you have seven days to adjust your profile just how you want. Depending on how much info you put on your profile and how long you've been using Facebook could determine if you'll need that much time, but at the end of the seven days, the change is permanent.

The Timeline lets people see all your Facebook activity instead of just the most recent items. The right side of the screen will now have the Timeline navigation where you can go back and look at your friends' activity to the time they were born. You can add more items to the time before you joined Facebook, called life events, and it will be like a new online scrapbook. But, if there are things you don't want to share, Facebook is giving you one week to make any changes. Start the slideshow to see the five things you should do first. Tell us in the comments if you like the Timeline.
