There is now a Discourse forum at

Intersect was a temporary VM running Discourse. This is to test the software as a possible replacement for Google Groups


Discourse has been installed as per these instructions. Currently it is relaying outgoing emails through Holly


Needs to support mailing list functionality. Seems to support send of the messages posted via email, if a little slow. Still need to investigate the following:

  • Reply by email
  • Start topic by email

Using Amazon S3 for uploads and backups. Keeps space used on the server to a minimum.

Everything runs in the container. Changes to container will be destroyed when it is rebuilt.

enter container (for logs, etc) using

root@server: /var/docker# ./launcher ssh app

logs are at (in the container)



To rebuild the app, use these commands:

root@server: /var/docker# ./launcher rebuild app
root@server: /var/docker# ssh-keygen -f "/root/.ssh/known_hosts" -R []:2222
