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 for each project member. In order to do this, navigate to the project's page within your dashboard, then proceed to the "Members" tab, then click on "Add Member" button.
In order to add new members, you will have to have their username, and not the display name. CurseForge staff will not provide this information via tickets or any other medium. 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, choose a role and percentage of Reward Program allocations (if you wish to), then click on done.
Please talk to other authors before adding them to your project, and do not add any author without consent, even if you fork their project.
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.
