Exactly and thanks for the feedback!

We have tried to make it super easy to start and join a Fridge. Just enter your email to create a group. To invite folks send them the group invite URL. All they have to do to join that group is click on it and enter their email and create a password. Hopefully this is a first step in making it dead simple to bring folks in to join or crate any group that needs a bit more privacy or is just a temporary network around an event so you don't have to friend people on facebook.
