Editing is more fun with friends and co-workers. With your Yapp account, you can create teams that give multiple people editing access to specific Yapps. (Note that in order to activate a team app, you will need to be subscribed to our Team plan.)
Creating a team is pretty simple. Start at your My Yapps dashboard and you'll see a drop down in the upper left corner, above your most recently published Yapp.
Click 'Create a Team' and enter your desired team name in the pop-up.
Once you've named your team, you'll be taken to the team's dashboard where you can invite other members, view the basic information about the team, and see the Yapps that you've shared with that team.
You can also create a team directly after signing up for a Team plan by entering a team name from the 'Congratulations' pop-up.
