No, you just need to go to that community while logged in with your lemmyworld account. Usually the url will become like this: http:// lemmy[dot]world/c/[email protected], and once you open that, you can post normally.
Yes, the point is to be able to participate in communities from all sorts of instances using your one account.
In fact, some people don't even have a Lemmy account, they subscribe to communities from mastodon or pleroma. It's not even the same kind of software but it's compatible.
You do not need to create an account on that node as long as they are federated. I am on mander.xyz but I can post to lemmy.world and I do not have an account on lemmy.world
this
To keep it simple, no, any lemmy account will work with any instance*
*As long as thag instance has not decided to de-federate(remove it's links to another instance of lemmy) from the instance you made you account on. (Looking at you beehaw)
If you don't want to, don't think about it too much.
From the user side of things, you don't have to worry about what instance a community comes from. If you like the content, just subscribe.
But, if you want to understand a bit more, here's a few things explained.
Here's a break down of the menus:
Subscribed: posts from communities you subscribe to, from your instance and other instances
Local: posts from the instance you signed up on
All: posts from all instances (that allow connections from your instance)
If a community is on your instance it will just be the name (ex: cats)
If it's from another instance it will have the @ with the instance name (ex: [email protected])
How does lemmy work?
Unlike reddit or other social media, lemmy is not hosted on one server, but serval smaller servers running on the backbone of the same software.
Each server is called an instance (examples: lemmy.world, lemmy.ml, lemmynsfw.com)
Think of it like forums back in the day, but a little different:
You can have forums that are general, and you can have forums that are more focused on a single topic or group of things.
just like these old forums, there are a few different general instances of lemmy, and also some more focused instances.
in these old forums, there could be threads with overlapping topics in several forums.
just like these forums, there can be overlapping communities in lemmy instances.
How is lemmy different from these old forums?
these old forums were almost all completely self contained, if you wanted to interact with another forum, you needed another account.
lemmy, on the other hand is federated meaning all if it's instances are connected.
Users can create one user account on just about any instances and that identity can be recognized on any instance.
This also means users can follow any of the communities from other instances as well.
What is federation?
Federation is a complicated thing, and has many uses and implementations, but if you'd like to know more about Lemmy's federation you can check out it's documentation on that here:
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
