For our students, it would be helpful if they would get a notification or an indication of unread comments in the ePortfolio.
E.g. a number of unread comments in your account information:
Additionally, in such a notification message a link to the page in the ePortfolio in which the comments have been placed would help the student find the comments more easily. If a student has 5 sections, and in each section 10 pages, it can take a while to find the new comments on each page.
