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.
You can’t on Lemmy, but can on mbin. I saw someone else mention just post, which will work for it, but I also just have a second account on a microblogging fedi platform for that, and that’s what I’d actually recommend for it. “You don’t need multiple accounts on the fediverse” yada yards, but there are certain instances where it’s helpful to have multiple, like this one xD
Mbin ftw
