How to Create and Use Instagram Groups
Instagram groups allow you to chat via text, image or video with anyone. You can easily create a group of up to 15 people inside your Instagram Direct Messages.
You can name your group and mute notifications to the group as well. To create a group, simply go to direct message and click the plus sign on the the top right. Search for profiles you want to add and press next. Now you can name your group and start sending messages.
