Hi Jazmin, You're correct; As Designed, Workfront has two special User fields on a Project: Owner and Sponsor. For many industries and clients, using one or both of those are sufficient. In other cases, though (to elaborate), Workfront Projects involve mire than just two Users, such as in my Oil & Gas example, where a "lead" from various disciplines (Geology, etc.) is specifically designated. The drop down of people (with a $$USER.ID friendly value for filtering) is an elegant way to model such additional Project to User relationships: it is simple, clear, enforceable, maintainable, results in a Project-level editable result set, and reportable (not only in that it can be used as a Filter, but also a View, Grouping, and Chart, which can be very useful).
