Over the next few weeks, everyone on Facebook is going to “upgrade” to Timeline, a profile update that shares your history and online activity since you first joined Facebook with… just about everyone. When you get Timeline, you will have seven days to preview the content — just enough time to delete your Spring Break pictures before your Mom finds them.

Like that baby book that your parents didn’t quite get around to finishing, you can fill in information from your pre-Facebook years (remember those?) using the new status update box, which is pretty easy to update with those special moments you don’t want to forget (or can’t really remember), like your first date or your 21st birthday party.

If you want to see how your timeline appears to other people, click the gear menu at the top of your timeline, and select “View As.” You can preview how your Timeline appears to a specific person or the public.

To feature something on your Timeline, scroll over the post and click the star to expand it to two columns. Or you can click the pencil to hide, delete or edit a post.

Use the Privacy dropdown to change who can see your posts. You can even select “Only Me” for posts you want to save but don’t want to be visible to others.

If you just can’t wait to share your Yearbook photos with your boss, you can get Timeline right now. Go to the Introducing Timeline page and click “Get Timeline.”
