For projects with multiple contributors and authors, you will want to add them as project members so they can help maintain and update your project. You can also allocate a percentage of Reward Program points to be distributed to each project member. In order to do this, navigate to the project's home page. Click the "Manage Project" button:

Navigate to the "Members" tab. In order too add new members, you will have to have their username. Once you have their username, simply search for their names, let results populate, and then click on the user you'd like to add to your project and then click the Add Member Button.

Once added, you will be able to change the member's role, what data they have access to, and what percentage of reward point allocations they will receive. You can also remove members from this page.
