Why do I get unlimited lives even though I don't have super/max?

French/Spanish/Portuguese-to-Esperanto all got removed a couple years ago. I’m guessing that OP joined the course before the removal was announced, and was grandfathered into it. Maybe infinite hearts are related to that.

I used to have unlimited hearts in the klingon course when it was in beta

It’s not, I’m on the esperanto course and I don’t have unlimited lives

I used to have unlimited hearts because of being a teacher using Duolingo schools, but a couple of days ago I lost this. I have had unlimited hearts for as long as I can remember. It seems to me like they are cracking down on that ‘loophole’, just not sure what the student accounts see now.

So you’re really into conlangs, huh?

I don’t think so. I don’t remember doing that.

Russian user here. Friend streaks are present, but some features like AI video calls are unavailable

Because it is a based language and there is a tiny but very welcoming community of speakers.

I didn’t know that. I am still in the French to Esperanto course as well, and I think I have started it three years ago.

I think those three courses got the axe about two years ago, likely because they were planning to kill the entire community program soon afterward. It was a real slap in the face to all the volunteers who were putting a lot of hard work into it. It looks like Spanish-to-Guaraní also got removed at some point. Here’s what the French section looks like today for me:

Why would you only want to learn a “useful” language? Language learning is a fun hobby and I’m pretty sure not everyone has a practical motive for it.

I understand you. But why do you have to be rude?

So what? I’m housebound but I’m still learning a language.

Right, I haven’t got any other Esperanto course than from English either. I didn’t know they had community courses but it sounds like a shame that they removed it indeed.

Oh yes, with the exception of a few more common European and East Asian languages, the large majority of the courses available today are the result of a volunteer-based project called Duolingo Incubator. It’s a shame; we used to get so many interesting new languages, but I guess that once Duolingo started earning profits, outsourcing labor to unpaid workers started to become a liability.
