Sign-in to HoL with just one click: social sign-in

Did you know you can shortcut all that email/password bother when you sign in to HoL?

For a couple of years now we've had a social sign-in feature which means that as long as you're signed in to your social network (Facebook, Twitter etc) you can sign-in to HoL with just one click.

I've just added a simple page on how to quickly set that up as part of our growing How to on HoL series.
