I work with various organizations on projects and will frequently create groups to share data. I add people to the group for the duration of the project but then delete the group once complete. But there is no way to "save" that person's profile for future projects. It would be useful if we can save a person's profile without having to search for them every time. And not have a "friend" list where they have to approve you (because as a state employee I wouldn't be approving many people) but just "save this profile" somehow so we can look up people easier.
