## What it is
Question2Answer (Q2A) is a free, open-source PHP/MySQL platform for building question-and-answer websites, used by tens of thousands of sites in 40 languages. It includes voting, reputation, tagging, categories, search, theming, and an extensive plugin system, with out-of-the-box WordPress and Joomla integration.

## Use cases
- build a stack overflow style Q&A site
- add a question and answer community to my website
- self-hosted forum for knowledge sharing
- create a support community with voting and best answers
- integrate Q&A into an existing WordPress site
- run a multilingual community Q&A platform
- set up a knowledge base with reputation points

## When to choose
- you want a self-hosted Q&A site on cheap shared PHP/MySQL hosting
- you need WordPress or Joomla single sign-on integration
- you want voting, reputation, tagging, and search out of the box
- you need a customizable platform with themes and plugins

## When to avoid
- you need a modern stack (Node, Python, containers) or API-first architecture
- you want a general discussion forum rather than Q&A format
- you need actively rapid development - releases are mostly maintenance fixes
- you require real-time chat or modern SPA frontend features

- function: search-engine, web-framework, plugin-system, templating, auth, rate-limiting
