The theme development forum was created to aid those who are developing themes for Drupal. This forum is not for issues you may be having with contrib themes. Issues with contrib themes should be placed in the issue queue of the theme in question. Please respect this.
If you you have drupal installed already and are seeking a theme, have a question about a specific theme and what it does or if it will fit your use case, please place your questions in the Post installation forum.
Let's say I have a blog with several authors/users who publish articles and, when the user clicks on the author, I want to display all articles from that author (without using views nor taxonomy. Or do I need to use taxonomy?).
I have a Content type COURSES which displays basic static information for a course: Title, Course Number and Course Description.
I also have a content type COURSE OFFERINGS that references the content type COURSE using an Entity Reference field. Each Course Offering displays specific information based on the Semester offered: Instructor, Date, Time, Location, etc. These variable all change based on semester.
