Zen Projects and Rahul have agreed to team up to bring substantial resources into the development of AnsPress and its related themes and extensions, read the full announcement here: https://anspress.net/blog/anspress-update-annoucement/
AnsPress is an open source, developer friendly, question and answer plugin for WordPress. AnsPress adds a full question and answer system to your existing WordPress site. It can be used to create a Q&A network similar to StackOverflow and Quora, or be a single page on existing site. The plugin supports multiple languages, shortcodes, reCAPTCHA, email and push notifications, and more.
AnsPress is not just limited to questions and answers. It can be used in many different ways, like a bug tracker, an internal Q&A board, support ticket forum, FAQ, and more. Anspress is trusted and used by many popular companies and sites at scale.
Performance and Optimizations:
In our latest release, we’ve made big improvements to performance and have tested the plugin in many different server environments. It has run smoothly on every type of server with minimal impact on load times. AnsPress (including all of its functionalities) is very fast compared to other Q&A plugins. In the latest release we have made major improvements to reduce MySQL queries and to increase the page load speed for all page templates within the plugin.
Developer Friendly:
AnsPress is built with developers in mind and can easily be extended to fit your needs. All parts of the template layouts can be overridden. Our source code follows WP coding standards and is properly commented. We are working on a documentation site which will be available soon.
Contributors:
This plugin wouldn’t be possible without the huge amount of contributions we have received. Check our contributors at https://anspress.net/contributors/

AnsPress – Question and answer

A free question and answer plugin for WordPress. Made with developers in mind, and highly customizable.

Boone Gorges

<a href="https://webwork.maa.org" rel="nofollow ugc">WeBWorK</a> is a free and open source online STEM assessment platform sponsored by the Mathematical Association of America (MAA) and used by more than a thousand colleges, universities, and high schools across the U.S. and around the world. The WeBWorK Open Problem Library provides access to more than 50,000 assessment/homework problems created and freely shared by the members of the WeBWorK community for others to curate, remix, and use with their students.
WeBWorK provides an option for students to email their professor if they have a question about a WeBWorK problem. However, this one-on-one communication model leaves students isolated from their peers and can result in the instructor answering the same question dozens of times. WeBWorK Q&A helps students learn from one another by sharing their questions in a community space. Instead of working on assignments alone or interacting only with their instructor, students using WeBWorK Q&A can become part of a community of learners, working together on the same material and offering mutual support. Questions can be answered by faculty, other students, tutors, and so on, enabling faster response times.
Features:
<ul>
<li>Ask questions anonymously</li>
<li>Use LaTeX in questions and responses</li>
<li>Include images in questions and responses</li>
<li>Browse and filter questions</li>
<li>Like helpful answers</li>
<li>Subscribe to or unsubscribe from email notifications about a question</li>
<li>Accessible, responsive recommended theme</li>
</ul>
