What Question2Answer is
Question2Answer is a free, open-source platform for running a question-and-answer community on a self-hosted website. Members can post questions and answers, search discussions, and organize them with categories or tags. They can vote, comment, follow questions, and use closed questions; reputation points, RSS, email notifications, and personal news feeds help track activity. Account management includes roles for experts, editors, moderators, and admins, along with avatars, custom fields, private messages, and public wall posts. Site owners can tailor the site with CSS themes, translations, sidebars, widgets, pages, links, and plugins. The platform integrates with WordPress and Joomla and supports custom single sign-on for other sites. The WordPress integration can use the site's existing users and database while storing Q&A data in separate tables in the same MySQL database. Captchas, moderation, and flagging are listed as spam controls. Requirements include PHP 5.4 or later with MySQLi and MySQL 5.0 or later. Question2Answer is licensed under the GNU General Public License version 2 or later, and community support is available through its Q&A site and Discord channel.
