I know it's been a long time, but I updated the plugin. Now it works with NodeBB 0.6.x.
The official plugin is:
I know it maybe remain a few problems with this plugin like special chars on steam nickname, I don't know how NodeBB is dealing with this. I'll try to keep a roadmap to this plugin.
There are 2 plugins listed on NPM about nodebb steam plugin. One was depecrated in favor of the new plugin name. I'll try to update the README of this one. Is there anyway to put a warning message when users tries to install this plugin from NodeBB ACP? Maybe add a warning on package.json... Just a thought.
