Site uses OpenID

When logged into another OpenID service,
The website will attempt to automatically log you in with your OpenID

- Sign out of all OpenID sites (Google uses OpenID)
- Visit the site, your prompted for username and password
- Sign in to Google
- Visit the site, and the site will attempt to login using your OpenID information (but fails because the site is invite only)

This all happens client-side
The website does not know your email address
This is no cause for concern
