In versions 1.8.5 to 1.8.8 of Chamilo, the term *Training* replaced the term *Course,* resulting in an awful lot of confusion, not only in English, but also in other languages which depended on English for translations. The term can be of course be redefined on each portal depending on needs through the portal administration interface, but *Course* is the term used globally now. * **Teacher :** The user who creates and/or controls a course (outwit h the *Session* context) * **Tutor** : See Coach * **User** : Any user who has an access to your Chamilo portal, regardless of his role --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
