Once you start to explore WebAssign, you'll see the "Communication" tab at the top. Click that and it will display under "Class Forums" a forum named "Class Chat". One of the topics is named "Introduce Yourself". Click on that topic, and then click "New Post" which takes you to a text box where you can write a paragraph about yourself as a way of introducing yourself to the class. Then click "Save".
This is not a class requirement, but it's a good way to promote the forum as a way of having contact with other students. And you'll get 5 free bonus points on your homework average (as incentive) if you do this during the month of August.
