Misago

Misago is a forum application for running community discussions, covering the features expected on a live internet forum: user accounts, categories with unlimited subcategory depth, threads, posts, and a full moderation toolset. Members register, set avatars, edit profiles, and reset forgotten passwords.

Posts can be written in GitHub flavored markdown, a BBCode subset, or both, with private threads, polls, attachments, best-answer marking, and an edit history that can revert changes. A moderation queue holds content for review, while ranks, roles, bans, and permissions control what each user can do.

Sign-in works through over 50 OAuth providers, and registration is guarded by email activation, Q&A challenges, ReCAPTCHA, and IP blacklists. Custom profile fields and GDPR-oriented settings round it out, and an OAuth2 client plus JSON API let you wire the forum into an existing site. The stack is Django on the back end with a React.js front end.
