DESCRIPTION
============

This file gives a brief guide to the Answers Module, which provides a question-answer service.

HOW IT WORKS
============

This module defines two content types, questions and answers related to questions. 

It defines views and page displays to work with them.

It has a series of submodules add:
- Best answer selection (flag) for its question
- Voting of questions and answers
- Integration with userpoints through rules


TYPES OF USERS
============

There are 6 relevant roles (these are not drupal system roles but rather types of users for the module):
1  Viewers: Those who view questions and answers
2  Question Authors: Those who ask a question.
3  Answer Authors: Those who answer a question
4  Site Administrator: Those who have the "administer settings" privilege and who can set up the module
5  Site Developer: Those who code sites using modules
6  Module Developers: Those who want to create modules using the Answers functionality

What the module does:
  Question Authors can create new questions by going to the path 'node/add/question' (in this approach, users are taken directly to the new question form)
  Question Authors can create new questions by going to the path 'questions/start_ask' (in this approach, users are asked to review questions that match theirs first)
  Viewers can review a list of all questions. This is available at the path 'questions/'
  Viewers can review a list of questions that match a search query. This is available at the path 'questions/search' [NOT YET RE-IMPLEMENTED]
  When viewing the list of questions, Viewers can sort by author, title, post date, and number of answers. If answers_voting is implemented, viewers can sort by votes. 
  When displaying a question, the system shows all the answers to that question. 
  When deleting a question, the system also deletes all of the answers to it. 
  Viewers can also see lists of questions they asked and they answered [NOT YET RE-IMPLEMENTED]
