Is there a way to "self-post" on Lemmy like there is on Reddit? - Lemmy.World

I can’t find any specific Yes / No via search and my understanding is that’s not really possible due to how federated websites work, so hopefully someone more knowledgeable than me can give me a straight answer. I had something I wanted to post that wasn’t very relevant to any particular community, but more specific to me, kinda like a blog post.

Unrelated but is there a way to convert someone else’s instance+community link to your own?

Obviously not faulting you for this, but when I click on your link I get taken to lemmy.zip, where I do not have an account so I cannot participate. I spent some time manually searching for that community on my own instance, which of course is a bit annoying for newbies and I would think there is a way around that I haven’t found yet.

Beauty of the fedi, you can post from one instance to another without needing a separate account. For example mine is a single person instance with no local comms, yet here I am.
