Nice! I ended up making 4 different accounts for the different instances I joined when I started all this because I was a dumbarse and didn't know what I was doing 😔
I think it works better with more logins. The link between instances is a bit buggy. Plus you can use each login for a different set of communities to create multiple custom feeds.
Hopping between them can be a bit of a bother, though. Since there's no way to move/migrate accounts to another instance just yet, you basically have to find and manually subscribe to the same communities for each account, if you want a shared feed.
Same here. I joined the main Lemmy.World one I think, which I still use. I honestly cannot remember how I found aussie.zone, possibly while I was searching for Melbourne on the other instance.
Searching it is the most likely option, since it's a lot easier to find an instance if someone else on the same instance has subscribed, and it syncs over.
If someone hasn't, you need to pop an exclamation mark on the front, so it actually checks the other instances, instead of just what's synced to your local instance, and if you're not familiar with that little tidbit (that's not on any of the search screens), it would seem like it doesn't exist.
