Facebook released a slew of new features, at their f8 conference and the Timeline looks like the shiniest one of the new goodies. Timeline isn't out to us regular users yet but rjcrystal, has found a way to enable Timeline by logging into the social network as a developer. This comes with a friendly warning though - the reason Facebook hasn't released the Timeline is because they're still fixing kinks and you may face bugs if you get Timeline ahead of time.Its officially releasing it on 3rd October 2011
Also, you will only be able to use Timeline on one device. If you open your Facebook account on another computer, Timeline will get disabled on both your machines. Finally, for one of the steps, you'll need to have a verified account, which means you need to have entered either a phone number or a credit card to your Facebook account.
However, if you're still hungry, here you go.
Step 1: Go to the Facebook developer page (developers.facebook.com)
Step 2: Click on Apps in the top bar. This will take you to a page where you will be asked permission to access basic information for the developer application. Click on allow.
Click on apps in the top bar
Step 3: You will then be taken to the apps page. In the top right corner, you'll see an icon "Create new app". Click on that.
Click on create a new app
Step 4: A box will pop up asking you to name your app and create a namespace for it. You can enter anything here (the namespace must not have been used before and Facebook will warn you if it has). After you plug this information in, you will then get a box wih a captcha code verifying that you aren't a bot.
You can enter anything here. The namespace must be more than 7 characters and no caps
Step 5: You will be taken to a page to work on your new app. Make sure you see the app name and app ID on the top of the page. Click on Open Graph in the left hand side panel.
Step 6: Once you are in the Open Graph page, you'll be prompted to enter an action (read, watch, plan) and a noun (book, television, trip) and then hit "Get Started). You will then be taken to a settings page. You need to change one of the default settings here. I changed the past tense of "Plan" to "Pland". Go through all three settings pages and make sure you're trying to submit your application to the public diary. Now wait 2-3 minutes.
Enter an action and a noun. Then hit "get started"
Step 7: Go to your Facebook homepage. An invitation to try Timeline will be hovering at the top of your page.
