I really like the fact that Archon now has the ability to limit repositories for users. That's a very helpful feature, and it should give Archon the ability to serve as a type of union catalog for multiple institutions.
One feature that would also be helpful, if it could be implemented, is the creation of a user role for a repository administrator. I envision this as a person who can edit information and user profiles for any repository to which he or she has rights. This would be different from the Archon administrator who has rights to edit anything pertaining to Archon.
