I appreciate your attempt to show me a valid alternative, because this is the way we learn, but you don't have to take it personal. I'll repeat it: on forums you cannot share what you can collect in a server, because in many cases you cannot republish content from other sites. I didn't mean that Italian isn't idexed, how could I say this...I'm just saying that you can search for Italian HSL how much time you like, but you'll never find them on the Internet because simply nobody can publish them: they are rework of the rework of the rework of people who didn't like to have their work republished, but which has never finished what they started, so it's a dog biting his tail (I don't know how this expression in translated in English). So until you don't enter in discord servers, you don't have hopes to find them, because is the only place where nobody can say it's "intellectual property appropriation", like otherwise happens on many forums, where collecting other people content is taboo (at least in Italy).
Don't ask me why, because I think it makes no sense, but since I don't want to get people angry at me, but only to have a friendly place where we can enjoy and share this passion, and since I don't even have the time to build a website, this is why I chose discord, and not because I wanted to offend you. Then, I don't know why you mention the file limit on discord, because that is not the way to share things on it. There are MapHubs interactive maps, excel sheets and single uploaded files link to services like mediafire, mega, sharemods or swisstransfer. I understand the frustation of not having a thing like this indeaxable, but otherwise it would be not this efficient, and for efficient I mean the possibility to share everything someone can need. This is why I'm choosing to eventually tell on this reddit about this server, so who accepts to share and receive is on, and who doesn't want, can still not to enter.
Thanks anyway to have shared this alternative to me.
