A More Expressive Like Button "Reactions"

Facebook has started testing its new like button today called "Reactions" with 6 different emoji namely  Like, Love, Haha, Yay, Wao, Sad and Angry. 
Here is Mark Zuckerberg post and video on launching and explaining new like button:

Today we're launching a test of Reactions -- a more expressive Like button.
The Like button has been a part of Facebook for a long time. Billions of Likes are made every day, and Liking things is a simple way to express yourself.
For many years though, people have asked us to add a "dislike" button. Not every moment is a good moment, and sometimes you just want a way to express empathy. These are important moments where you need the power to share more than ever, and a Like might not be the best way to express yourself.

At a recent Townhall Q&A, I shared with our community that we've spent a lot of time thinking about the best way to give you better options for expressing yourself, while keeping the experience simple and respectful. Today we're starting to test this.
Reactions gives you new ways to express love, awe, humor and sadness. It's not a dislike button, but it does give you the power to easily express sorrow and empathy -- in addition to delight and warmth. You’ll be able to express these reactions by long pressing or hovering over the Like button.
We’re starting to test Reactions in Ireland and Spain and will learn from this before we bring the experience to everyone. We hope you like this – or can better express how you’re feeling!

How To Publish Actions On Timeline (Updated)

On 31st May Facebook had announced few changes in open graph approval process and also Updated Open Graph Publishing Guidelines in which some important parts were:

Additional publishing guideline
For stories about watching a video or reading an article, you must use the built-in watch and read actions. We’ll no longer approve custom actions for these stories.

90-day update window

• Even if we’ve approved your custom action for reading an article or watching a video, you must migrate to using a built-in action, resubmit your app and get approved. Please review the requirements for working with read and watch actions.
• Built-in watch and read actions can only be published after someone engages with the content for 10 or more seconds. If a video is shorter than 10 seconds, the viewer must watch the entire video.
• Tagging people and places:

• Only encourage people to tag friends when they have actually performed an action together.
• Only encourage people to tag a location if they are currently at that place

So according to guidelines above developers have to use built-in actions instead of custom read and watch actions and also to post action only when user engages with the content for 10 or more seconds, to meet these requirements I thought I should write an updated tutorial on it because in my earlier tutorial on How to publish actions on timeline we had used custom actions to post on users timeline.

How To Get Access Token For Publishing Action On Timeline

In my earlier tutorial on How to publish actions on timeline i showed you how to get access token manually in step 3, but the problem with this method is that the access token will expire after every two hours and you have to copy the token again and again.

To solve this problem i found this tutorial in Facebook developers blog which handles the following issues in which access token become invalid or expired.

Note: By default open graph settings access token is not necessary for publishing on users timeline if the action is for the same page from where it is triggered otherwise its necessary to have access token for publishing.

How To Forward Emails Automatically To Facebook Inbox

It's been awhile since Facebook launched its new messaging system with the option to get username@facebook.com email address. If you have already claimed your Facebook email address then you can forward all your incoming emails automatically from Gmail to your Facebook inbox.

Why to forward emails to Facebook

The benefit of forwarding you all emails to Facebook automatically is you don’t have to go to every email account to check for new emails and secondly you will be notified when you will receive a message in your inbox.
