General purpose comment module. Although a simple module, comments can add a lot of interactivity to your community resources. Configuration of this module is easy: it primarily depends on a ParentEntityId / ParentEntityType pair of properties, where the first one defines the Id of the entity your are commenting, and the second one is used to specify the type of the parent entity (SnEntityType enum can hold values for Album, Message, Note, BlogPost, ...). You can use Custom entity types for linking comments for other types of content. It can be done programatically or via Web part communication - comments part is a connection consumer, and provider parts have to implement the ISnRelationshipConnection interface and provide a method decorated with ConnectionProvider attribute.
