Integration with Virtuemart login

For Virtuemart, what you say is correct. Once the account is created with JFBConnect, they can login with Facebook or their Joomla credentials when they return. In either case, there shouldn't be any other forms to fill out.. unless you have Virtuemart or something else configured to get more information from the user.

Not sure why you're getting the white pop-up box. That's a known issue with Facebook Connect that happens periodically. It could be something new we need to work around, or it could just be a temporary glitch in their Javascript.

Thanks for pointing it out,
Alex
