What is the difference between OpenID or Signed up user?
OpenID eliminates the need for multiple usernames across different websites. We support OpenID login, which means if you have an account in Yahoo, AOL, WordPress, Blogger, myOpenID etc you can login without registering in DotNetShoutout. If you do not have any OpenID account, you can get one free from here. There is no difference between OpenID and signed up users, we treat both the same. However, some of the OpenID providers do not provide email address of user, which is required to get the complete benefits of DotNetShoutout (e.g. comment notification via mail).
