+# Mission
+
+Our mission is to make the learning experience great for tens of thousands of students around the world.

-# CURRENT PROBLEMS TO BE SOLVED
-1.  a new user could not login immediately after sign-up. (SOLVED)
-2.  password resetting link is not always sent successfully.
-3. creating sub-directories on all student submissions course-code/semester/section-number.  (/student-number/course-code/semester/section-number/assignement-title/submission.txt)
-4. editing the assignment title after uploading a new assignment (instructor).
 
-More improvements are welcome
