A group is a collection of your vialogues that you can share with a specific set of people. It simplifies the vialogue sharing process by allowing you to grant multiple people access to multiple vialogues all at once. In other words, if you have 20 vialogues that you want 10 people to watch and discuss, you could put all the vialogues in a group and add your participants to it in one move rather than add the 10 participants 20 times to each vialogue.All groups are private. At this time, there is no way to have a public group. If you want to organize your vialogues for easy public consumption, we suggest using our hashtag feature.
