Hi all, this post is really just for awareness about some fairly new Yammer content that was recently published.  Our documentation team has prepared a poster for Yammer on Mobile Devices, which covers both applications and their features that we currently offer for mobile devices, but also has a nice section on authentication options with Yammer.  There is still a little fleshing out needed around the single sign on option for Yammer, but I'm hoping that it will be further updated in the next couple of months or so.  In the meanwhile it's a great starting point to learn quickly and simply what you can do with Yammer on a variety of different mobile devices and operating systems.  You can check it out at http://technet.microsoft.com/en-us/library/dn635312(v=office.15).aspx.
