Facebook Connect is an optional Principals' Test Website feature that, if enabled, allows for quicker registrations by automatically using information from your existing Facebook account on this site. If you have previously registered you may use Facebook Connect to link your site account with your Facebook profile.
Besides quicker registrations the other benefit of using Facebook Connect is, if enabled, you will be given the option of publishing the content you post to your Facebook Wall at the same time you submit it to this site. To use this feature look for a "Publish to Facebook" checkbox under the main editor box before submitting your post.
You may add or sever the Facebook link at any time by going to your username at the top of the page, and choosing "User Settings." Next click on the "Accounts" tab and finally scroll down to "Facebook Connect" and you may connect or disconnect from Facebook.
