Hehe. It was a veerry lucky situation.

I sent a message to someone telling that I was working on backlog.md and it turned the name into a link automatically.

I wanted to remove the link and I clicked on it accidentally and discovered that not only there was nothing on that domain but was not registered yet. I got the domain few mins later :)

It's the gTLD for Moldova, seems to have limited registrar availability[0] but there's no residency/association restriction like some countries impose so anyone can get one. I've seen markdown related projects use it here and there like obsidian.md
