If you are running into issues with the Facebook link, here are a few things to try:
Be sure that you have your pop-up blocker turned off on your internet browser.
You can only have one (1) email address registered to your Facebook account, so double-check that there aren't multiple emails listed on the account.
Be sure that your email is verified on Facebook.
Set your email privacy settings on Facebook to the lowest setting, to prevent it from blocking access through our site.
Go to your Facebook settings and removed TutorMe from the websites tab. Then return to TutorMe and selected the sign-in option again.
