webcomm10, i think i am looking for what you described as well.
did you figure anything out?
i want:
new user visits site and click on Connect With Facebook or whatever and it then recognizes that they are already logged into facebook and seamlessly creates them a wordpress account. They do nothing. No checking their email for a password or anything. They just click connect, it does its thing then redirects them back to the hompage and shows that they are connected (maybe the profile pic displays somewhere?)
thats my idea. How can we do this?
