[Bulletin Board for CSNS]

For this assignment, complete the following features of the CSNS bulletin board described in Homework 3:

• (25pt) Display all the forums. The general forums should be listed first, followed by the course forums. And for each forum, display the forum name, number of topics and posts, and the username and the timestamp of the last post. See the ACM forums page for example.
• (25pt) Display all the topics in a forum. For each topic, display the topic name, author, number of replies and views, and the username and the timestamp of the last post. The topics should be ordered by the time of creation, with the most recently created topic first. Paging display must be implemented with 5 topics per page. See the CS520 forum page for example.
• (30pt) Create new topic. Validation must be in place to ensure that a user cannot create a topic with no subject or content. You do not need to implement file attachment for this assignment.

[Extra Credit] (Up to 20pt)

Listing all 200 course forums on the forums page make it rather difficult for a user to find the forum he or she is interested in. Come up with a better user interface design to solve this problem. Note that you won't receive any extra credit if you simply use paging for the forums page.
