How to activate timeline on facebook?

[Edward]

First log in to your Facebook account. Secondly, go to the page http://www.facebook.com/about/timeline, which you can access by clicking here.

On that page, at its bottom right hand corner, you will see a large green button that says “Get Timeline.” Click on it and your profile will be changed for the Facebook Timeline. [Update: Many users reported that they still don't have the green button. Some of them tried different browsers and computers but the button still wasn't there. As members from the same family using the same computer had different results, this can only mean that the upgrade is not yet available for some users. A good way to go about it is to try once a day until the button appears. As soon as there is some news about this issue I'll include it in this article.]

Once you get Timeline, you'll have seven days before anyone else can see it. As Facebook states, this gives you a chance to get your timeline looking the way you want before other people see it.

Although once you get Timeline you will not be able to switch back to the old design, this is not important because the change is being applied gradually to all the Facebook users.
