Askbot

Askbot is open source software used to create question and answer oriented Internet forums.

The site started in July 2009,[2] initially similar to Stack Overflow or Yahoo!

[3] Based on CNPROG[4][5] and some code written for OSQA, it is primarily developed and maintained by Evgeny Fadeev.

Askbot can be easily installed by using the documentation[7] on Ubuntu and CentOS.

[8] and LibreOffice used Askbot for Q&A but they decided to migrate to Discourse,[9] as Fedora had done before with its Q&A.
