Hi Folks, thanks for testing the site, I've released the third beta of qa-stack, this release includes JANRAIN login, use your google, yahoo, openid/myopenid accounts to log in into the site, and feel free to post test questions and answers, there are still many things to work out but at least you can get a feel of what is to come.
Site is http://beta.qa-stack.com/ qa-stack uses a "point" system to "advance" the user to higher "roles", which in turn allows you to do "more stuff" on the site, like ban questions, edit other user's data, mark questions as featured, mark answers as outstanding, etc. However, a user with lower roles can be "upgraded" to a higher role by a SysAdmin, this will give you lots of flexibility, there will be about 5 more cycles of beta releases and finally a version you can download yourselves and test locally, etc. Merry Christmas, Julio
