I had a look and it is a "Private Group", so I guess you'll need an invite (sorry about the confusion, I should have looked further before I mentioned it here!)
If anyone wants in, just send me a Friend Request (Mark Kirk... my profile picture is Grampy from Betty Boop, so you won't request from the wrong Mark Kirk) and I'll send you an invite.

Just sent you a FB request.

I did likewise. Thanks for accepting, Mark!

Hello Mark. I just sent you a friend request on FB as well. I’d love to get an invite to the Cherry Smash Revisited group. Thanks!

Too confusing.
