At the bottom right of every page, you can click on the “Instances” button (or just go to https://lemmy.zip/instances) to see what instances your site is federated with/is defederated from. lemmy.ml is under linked, so lemmy.zip is federating with them.

What you may be running into is that on this smaller instance, you may need to discover the communities:

These previous ways [searching for instances] will only show communities that are already known to the instance. Especially if you joined a small or inactive Lemmy instance, there will be few communities to discover. You can find more communities by browsing different Lemmy instances, or using the Lemmy Community Browser. When you found a community that you want to follow, enter its URL (e.g. https://feddit.de/c/main) or the identifier (e.g. !main@feddit.de) into the search field of your own Lemmy instance. Lemmy will then fetch the community from its original instance, and allow you to interact with it. The same method also works to fetch users, posts or comments from other instances.

This whole website is great, thanks for sharing! Currently hooked on drawing a perfect circle

Pixel 6a - was happily using a Pixel 5a for the past ~2 years until it had a spontaneous motherboard failure 3 weeks ago 🙃. Google replaced it with a 6a, I’m still annoyed the 5a can become a brick with no warning but I’m very happy with the 6a with GrapheneOS so far and plan to stick with it until the OS updates stop.
