[Comments] are informal messages or feedback. They can be attached to many places, for example a personal note, a community, a community forum or community forum contribution, a review, an external reference, or another comment.
Sometimes specific names are used for comments depending on what they are attached to. For example: * a personal note comment is a comment attached to a personal note. * a forum comment is a comment attached to a community forum either directly or via a community forum contribution. * a comment reply is a comment attached to another comment.
The ability to reply to a comment (or a comment reply) means that comments can be chained together to show a detailed conversation on a topic.
The owner of a personal profile or the administrator of a community are able to remove inappropriate or out-of-date comments attached to their personal profile or community respectively.
