GooglePlus Community Page
I have created a Google+ community page devoted to Vanguard. I try and post there every day on my thoughts, aspirations, and questions about the game. I would definitely like to see more people join up because it only makes the experience more enjoyable.
I think all you need to join is a gmail account. I do not have the rights to post the URL, but if you go to the Communities page and search for Vanguard you should be able to find the site.
