Answer 1

Create a web page with the required form elements.

A simple table stucture you could use is:

Topic table
ID, id of the table
Author, who posted the topic
Title, title of the topic
Body, message of the topic

Comment table
ID
topicID, The ID of the topic this belongs to
Author
Body

You would then add new topics and comments to the correct table and link them using the Topic ID
