Can someone tell me how multiple-opening authentication works in Stack Overflow? I have this doubt since I want to implement the same functionality on my new magento site. The only doubt I have is that if I log in using openID, I will use my unique URL (for example: http://example.myopenid.com). Now that I want to do something, I have to receive an email confirming how to get it without typing it anywhere?
A similar scenario is on the current site, i.e. stackoverflow.com. I am posting this question using my openid authentication. Now, how can I find out if someone is answering my question, or is someone commenting on it? Please help me know this.
