As of Discourse 2.5.0 beta 3 Merge users is built into Discourse
This plugin will not be supported long term and may break soon…
With this plugin you can easily merge two users together.
Just add one line to your app.yml:
hooks: after_code: - exec: cd: $home/plugins cmd: - git clone https://github.com/discourse/docker_manager.git - git clone https://github.com/curiousdannii/discourse-merge-users.git
Then rebuild the container:
cd /var/discourse sudo ./launcher rebuild app
