The id you send should identify the user in your system. The plugin will store a map of NodeBB user id to your id for synchronization.
Any plan of supporting them in NODEBB?
Possibly as category replacement?
Hey @Giorgio-Chiodi -- there's this plugin: https://community.nodebb.org/topic/634/-nodebb-plugin-twitter-hashtag-twitter-hashtag-plugin#7953, but it just uses twitter's system, and doesn't involve NodeBB, really.
Something as major as replacing the category system is interesting, and we haven't really thought hard about it yet, but it's definitely something people want
Actually, what are the brackets for in the title? Could they be used as tags?
Go tags go!
