Teaching and learning mathematics at university level is increasingly being supported by Learning Management Systems. In this chapter, we report from the e-learning initiative, DELTA, and in doing so we aim to describe how formulas, drawings, and other mathematical representations influence student communication. We describe a practice that combines handwriting and discussion forums facilitated by a Learning Management System (LMS). We have experienced lack of student activity in the discussion forums and introducing a new LMS (Moodle) with improved formula editor capabilities into the environment, does not seem to considerably improve the situation, whereas a scanner-based handwritten communication seems to successfully support the assignment communication between the students and the teacher.
