Now we have a chance to see a new Facebook feature – a new Send button on websites along with the Like button, and this new Send button will improve the functionality of Groups and it should replace the old email to a friend button.
When you click the Send button, a pop-up will appear that allows you to send the article that you’re reading to your friends, groups, or to a specific email address. Of course, you can add your own message and forward the page to your friends’ inboxes or to the specific Group wall.
This button is designed so that you can share pages with a close groups of friends, and so far, more than 50 websites are using the Send button. The new Send button is a great addition, and if you want it on your site, you can get the code for it on the Facebook’s Developer Website.
