Dive is more fun when you bring your tribe on board.
There are different ways to invite people to Dive.
Invite people from the Dive home page
Invite people while you sign up or once you reach the home page. Click on Invite people and add email IDs of people you'd like to invite.
Invite by copying a Dive room link
Copy a Dive room link and send it to people via email or Slack. You can alternatively paste it in a calendar invite too.
