I recently spun up my own lemmy instance and was wondering if I had to manually add other lemmy instances to the ‘Allowed Instances’ admin field, or if they are added automatically when someone searches for a lemmy instance?
I wondered the same, so I added a few to the list and now I can sub to communities by taking the url and then searching within my local instance. Hope thay helps.
I noticed when I go to the ‘popular’ lemmy instances such as lemmy.world and lemmy.ml and click on communities | All that I see a lot of communities. On my own local server I only see the communities that I’ve subscribed to. Is that what you see as well?
You have 3 options of viewing posts in regards to where they’re posted, choose all for everything across the fediverse, also you click where it says new to view posts based on either date of post or popularity of post, lemmy is cool in that way, much easier to find old posts than gab, twitter or scored (not sure if that answered your question)
Yes, your instance will only ‘know’ about communities that you have searched for from your instance. Once you search for some, they will appear under “All” communities. However your instance will only receive updates for those communities if at least 1 person on your instance has subscribed to them.
