We made it super easy to invite friends into a Fridge group. Every group has a private invite URL that you can distribute via any one of those platforms. User click it, create a password, and they are in. The group can be small for a few friends or large for an event. Context stays within the group.

Why would you use the Fridge instead of what you are doing right now? With Facebook most people don't really know how to customize their privacy settings and you have no idea how all your friends have it set. If someone shares something with you how do you know their settings aren't public?

And using email has it's own set of problems like long reply alls. Subject matter gets lost in branched conversations. People get added or deleted along the way and emails get lost in a sea of email bankruptcy.

We aren't solving that problem but trying to provide a better platform to interact in groups.
