Change tracking and collaborative communication are provided in authoring content in a collaborative environment. Monitored changes, comments, and similar input by the collaborating authors may be presented on demand or automatically to each author based on changes and/or comments that affect a particular author, that author's portion of collaborated content, type of changes/comments, or similar criteria. Change and/or comments notification may be provided in a complementary user interface of the collaborative authoring application or through a separate communication application such as email or text messaging.
