I have been using Lemmy for 20 days, at first I opened an account at Lemmy.world because you can join without writing a text and waiting approval. I have been enjoying the experience overall but despite the admin teans best efforts Lemmy.world has been experiencing some serious performance issues. If you want to avoid that join a smaller instance, preferably hosted in your country. I joined discuss.tchncs.de today and everything is so much faster it has added benefit of being able to see beehaw.org posts too. It will improve not only your but all other Lemmy.world users experience too.
I’m having trouble understanding how this works. If i create a community on a different instance, why can’t i find it here, even when i have the switch set to all? Do they only sync on certain times of the day? Also when i delete a community (that i created by accident) why does it not disappear?
Federation happens gradually and changes are usually not visible everywhere at the same time. Using a fully qualified name (or an URL like
https://lemmy.world/c/community@instance) you should be able to access your new community though.
