I tried to sign in to Lemmy.ca with the account I created on the Lemmy.ml and it didn’t work. Any reason for this? (I am very new to Lemmy and am still learning how to use/understand how all the instances work)
You can think of Lemmy and federation like email. You can receive and read yahoo mail on your gmail account, but you obviously can’t login to yahoo with your gmail account. Lemmy works the same way more or less except these "emails” (posts and comments and upvotes etc… ) aren’t private but public. You can see and interact with lemmy.ca’s posts from here on lemmy.ml by clicking on "all” as opposed to ”local” on the front-page. That’s where the posts from lemmy.ca get ”pulled” to lemmy.ml, and if you comment the comment gets sent to lemmy.ca.

This is the clearest explanation I have heard, thanks!
