A Collaborator is a user who decides to support any project that is open for Collaborations (without necessarily funding financially). A user may work on a project, share ideas, give suggestions to the Founder or be working for the campaign as part of the team. The Collaborator can give an update to the project of a Founder with a content related to the project using the special-tag to contribute to earned HeartPower rewards for the benefit of the total goal of a project.
