Comments placed on profiles should be relevant to that person and their data. Sometimes non-relevant comments are placed there and should be removed which can only be done by the person that placed it.
An example is a comment on Richard Olmstead-7 created by an individual 16 months ago who joined, made only three contributions, and then disappeared.
The manager, and for this profile, the PGM project should have the ability to removed such a comment.
An individual would be welcome to put a comment on their own profile claiming descent from a historical person.
