I'm having some trouble trying to make an area on my WordPress site, that must be accessible only to members of my Google Group. I tried to make it with some plugin, but most of them would take me to have to ask the users to register themselves in the website, and that would not include a validator to see if he is a member of the Google group.
So, my point is: Is there any way to make a area of my website themselves accessible only by members of a Google Group? If so, how could I do that?
