Micro-letters automatically log in and get nicknames for examples

Record only: Micro-credit get nickname Auto Login
After several repeated verification, I found this method is flawed:
The micro-letter did not pay attention to access to the site, can not get nickname.
After paying attention, I can get a nickname with this method.
Is the nickname not generated because of the first generation of OpenID? Pending Test.
