Yep, no worries.

Heck I don’t know what “list” means!

OK then, we'll start with the basics - a list is just a collection of various items. In the Fediverse you can follow people on the bulk of the services and communities on here. So they are basically the items you'll be adding to your list.

Bear in mind that:

• I'm still figuring this all out.
• My examples are using Tusky, other Mastodon apps exist.
• I have largely decamped to Calckey.

So the first thing you want to do is follow someone. I will follow you on here for this example.

I hit the search button and add your user ID into search:

I click through and hit "follow". Happy days.

I assume you are good up to here.

Then on the home page I press my avatar to get the side menu up and we want the 'lists" option:

There's a big + on this screen to add a new list, so I hit that and get the panel to give it a name.

Then hit "create a list".and it tags it on the end of any other lists you have. Hitting the ellipsis ... gets you the option to edit it, along with other other things you may need to manage the list:

Hit a bit of a bump as you need to accept my follow request for this bit to work so I'll use another example:

Hit + and it turns to an X (so you can remove them from the list). They are now in your list and, when there are new posts, that list will start to fill up with content.

Hope that helped.
