Everyone can participate here from another instance, that’s the “magic” of the fediverse. For example if your home instance (where you signed up initially) on sh.itjust.works, you will see it under https://sh.itjust.works/c/patriots@lemmy.ml so your home instance (sh.itjust.works) will have its own copy of this sub and will replicate everything there - you will be able to comment/post/upvote just like everyone, while the sh.itjust.works & lemmy.ml replicate in the background.

The current problem is that lemmy.ml is overwhelmed so can barely keep up and can’t federate the changes, so you can’t see this post on sh.itjust.works for example 😞 but I’m sure things will get sorted out soon
