That's not how it works.
- You need to set up an account on a Lemmy instance and log into it using Connect.
- You can then subscribe to specific communities with that identity.
- If you want to have different types of feeds, set up different identities, ideally on different instances.
- 'All' is basically 'new' for everything that anyone on that instances subscribe to
- 'Local' is what's new for that instance
- 'Front page' is what you are subscribed to
- If you check top right there are various sorting algorithms such as 'hot'/ 'active'/'top'
