The Web Forum site includes an interactive module that can be entered only by registered users and that allows them to perform the following activities:

• To create news that are then published in the news board within the public module;
• To access discussion rooms and post messages within a selected room. Posted messages can be both new questions, opening a new discussion, or also answers to questions posted by other users.

For each posted news and message, it is necessary to keep trace of the author.

Given the previous requirements, within the interactive module define:

• A content management fragment for the creation of a new question in a discussion room by a registered user. The new message must be associated to the previously selected room and to its author;
• A content management fragment for the creation by a registered user of an answer to a question posted in a discussion room. The answer must be associated to the original question and to its author.
