"Send from Gmail is one of our favourite Chrome apps we have been using for some years now. Send from Gmail provides you with a quick way to share web links and other online resources with a single click. For instance, if you are reading a blog post that you want to share with one of your colleagues, you simply click on 'Send from Gmail' button and a new compose window will automatically open with the page title as the subject and selected page text and link address as the message. All you have to do is to simply type in your addressee's email and hit 'send'."
