We have many projects which are meant to be portals / umbrellas for information only as repositories for sub-projects (related projects). The portals are requested, "please add no profiles," but there's no way to enforce it. Additionally, some projects may be completely populated according to their objective, but there's no real way to prevent additional and unwanted profiles to be added.
Can we have a option (by the profile creator?) to "lock" the project to "no profiles," and an unlock mechanism also (if conditions change).
