This file gives a brief guide to the Answers Module.

Last Updated: 5/21/11 by Chip Cleary

This module is based on:
•	The original D5 "answers" module written by Amanuel Tewolde.
•	The original D6 conversion of that module written by Inders Singh
•	The original features version of the module written by Greg Harvey
•	The updated features version of the module written by me.

There are 5 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

What the module does:
•	Users can create new questions by going to the path 'node/add/question' (in this approach, users are taken directly to the new question form)
•	Users 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/all'
•	Viewers can review a list of unanswered questions. This is available at the path 'questions/unanswered'
•	Viewers can review a list of questions that match a search query. This is available at the path 'questions/search'
•	When viewing the list of questions, viewers can sort by title, post date, and page views
•	When displaying a question, the system shows all the answers to that question. 
•	When deleting a question, also delete all of the answers to it. 

1. Viewer Role:
•	The module offers some predefined views to see lists of questions
    - 'questions/all': A list of all questions
    - 'questions/unanswered': A list of questions without answers
    - 'questions/search': A form to search for questions
•	Users can view an individual question along with its responses.
•	Users can vote a question thumbs up or thumbs down is he has permission.

2. Question Author Role:
•	Users can ask a new question if they have permission. They can do so at 'node/add/question' or by using the Create Content -> Question menu item
•	When a user asks a new question, the user can specify whether they want to be notified by email when an answer is posted. This is a checkbox setting on the form used to create the question.

3. Answer Author Role:
•	When viewing a question, a user can enter a new answer if he has permission. This is done by using the 'Post an Answer' link on the question node view.

4. Site Administrator Role: Site Administrators can define:
•	Which drupal system roles can view questions and answers (by setting the permission 'access content')
•	Which drupal system roles can ask a new question (by setting the  permission 'create question content')
•	Which drupal system roles can answer questions (by setting the permission 'create answer content')
•	Which drupal system roles can vote responses up/down (by setting the permission 'use vote up/down on nodes')
•	Which drupal system roles can see the tally of up/down votes(by setting the permission 'use vote up/down on nodes')
•	Whether users can edit or delete their own or others questions and answers (by setting the corresponding permissions)
•	The subject and body templates for an email notification (using the path 'admin/settings/answers')

5. Site Developer Role: 

5.1 To set up the module:
•	Install the module
•	Configure the administration options (see "Administrator Role" above)

5.2 A few pointers on how it works:
•	The module was developed using the Features module
•	It defines two CCK types: Question and Answer
•	It defines a couple of views: all_questions and question answers
•	It defines a couple of strongarm variables: 'answers_answer_notification_subject' and 'answers_answer_notification_body'
•	It employs a small amount of custom code to:
	•	Provide administrative settings
	•	Send notification emails
	•	Make some nice adjustments to the search and new question forms	
	•	Hide the notification option when anonymoous users add questions.

5.3 Site Developer tips:
•	If you want to automatically search for questions that contain a string ...
    => You can use the path 'questions/search?keys=your-string'
•	If you want to lock a question so that viewers can no longer post new answers
    => Set $question_node->field_question_locked_p[0]['value'] = 1; (Or set it to 0 to unlock a question)
•	If you want users to ask a question but search for it first, send them to:
    => 'questions/start_ask' (if they don't yet have a question)
    => 'questions/continue_ask?keys=question-string' (if you do have a question string already)
