You can add multiple people to specific groups, too. You will need to be an administrator of the group in order to invite and manage members.
Once a group is created, here are the steps you need to follow to invite members to that specific group:
Select a group via the menu on the top left corner shown in the image above. In the top-right corner, click on "add members"
- Select the members you want to invite, and click 'add'. The user will automatically be added to the group and an email will be sent-out informing the user. You also have the option to add a personalized invitation message.
