1) Awesome! Glad to hear that worked.
2) When you're testing auto-login, please make sure you're clearing your browser cookies or closing the browser altogether. Then, open a page tab and go to Facebook.com. Login there. Then go to your site. You should be automatically logged in.
If you're testing after clicking the logout button on your site, there is a window where automatic login is disabled to prevent a user from not really being logged out.
3) We'll have to investigate our Pinterest code more. The problem is that the image tag we're setting is, for some reason, using some random Javascript that jReviews adds. We haven't heard of that issue, and I can't imagine why it's doing what it's doing. I'll let you know what we find, but for now, obviously, leave that disabled.
Thanks,
Alex
