Enabling administrators to add researchers as collaborators

[ann-james]

Requesting DMPTool add functionality to DMPTool.org's data management planning tool that enables administrators to add researchers as collaborators manually. In the past few years, I've observed a number of researchers who have experienced challenges adding themselves, colleagues, and/or collaborating reviewers to data management plans in the online interface. DMPTool's Product Manager recommended that I make a formal request for this functionality thru this github space. Thanks for considering.
