i am not signed it, and I still read the article. I keep hearing this complain all the time with google groups. Is it specific to only few or are they based on assumption that it's a google group?
It's a weird bug with Google Groups. As far as I can tell, if you aren't signed into any Google service at the time, it will let you in. But if you are signed into another Google service, Groups will demand you re-authenticate.
