I created a lemmy community for the free and open source inventory and ticketing system GLPI, I use it in my lab, and maybe some of you does too!
Wanderer is pretty fun, more user curated things, some are shitty some are high quality, depends, plus you can just contrubute your route too! And the fact that it’s activity pub powered is a nice bonus
It is enabled by default, you just need other server to be able to contact your server by https. Then you’ll see other servers content on your timeline, of course as always with activity pub, you might need to kickstart it by following a few people first.
You can also follow people from a wanderer instance on mstdon then you’ll get posts with links to the trails :)
