IndieForums

 IndieForums  is an IndieWeb friendly forum that allows users to post content or replies on their own site and cross post to the forum automatically using Webmention notifications both to the forum itself and to the original posts on other authors' websites.

The site was built by Tim Culverhouse as a proof-of-concept in May 2021. The code for the site is available on GitHub: https://github.com/rockorager/indieforums.

The project was built using:
 * 11ty to build the site
 * Github to host the repository
 * Netlify to host the site
 * Webmention.io to receive webmentions

Similar sorts of discovery services can be seen in IndieNews and Indieweb.xyz.
