I need you to suggest a PHP script to manage a "Question / Answer" websites.
The system needs to include the following features:
1. Admin can create categories / subcategories / sub sub categories..
2. they can they add a question in more than one category..
3. The question needs to have 3 fields (title + Question + answer)
4. also each entry needs to have an ID #
The example of what i'm looking for is located at this link:
[login to view URL]
i'm not looking for a "custom made" system.
I just want you to suggest one good PHP system for me to install on my server.
