The installation was without problems. I've had a little troubles to set a language (I use on my web) inside the login form. The support (Cameron) responded very quicky and within couple of hours everything was set up and worked just WONDERFULLY!
Thanks so much for the review. JFacebook is evolving with the needs of its users, and the VirtueMart module is one such example.
Good Luck with your endeavors.
