Please follow link or @link to subcategory that best suits the topics on your site. If your site covers multiple topic areas please add it to the E-learning Portals category found in the list. If a site offers Correspondence_Courses please suggest it to Reference/Education/Distance_Learning/Correspondence_Courses Correspondence courses are classes which are completed with course material and assignments mailed the 'old-fashioned' way between the instructor/grader and student. It is also possible that email may be used instead of physically mailing assignments.
