title: C# google login
body: <p>I'm maintaining some code that I want to add a chat feature to. I already have a client/server/database setup, but what I would like to do is use Google accounts for logins, instead of people having to create new accounts and such. 
  Could anyone point me in the right direction? 
  I've already downloaded this <a href="http://code.google.com/p/google-gdata/" rel="nofollow">http://code.google.com/p/google-gdata/</a> Am I on the right track?</p>
  
  <p>Just to clarify as well, this isn't an asp project, it's a desktop project.</p>
