I saw a post form somewhere on jlailu in the feed here, but it’s gone now.
They’ve got subs /r/france and /r/forumlibre. How can I join them without making an account over there? Is there any interface other than just hand writing out what the url would be?
Your instance is the web domain that is hosting Lemmy. So, the instance you joined is lemmy.world. There are many instances, like lemmy.world, such as lemmy.zip, lemmy.today, lemmy.ca, and lemmy.ml (just to name a few). Additionally, there’s Piefed, and there are Piefed instances like Piefed.social (where I reside), piefed.world, etc. These instances all share content via “federation”.
When you’re logged into lemmy.world, you can use the built in search features to find communities (subreddits) you want to subscribe to, to see content posted there on your home feed.
