I want to take a crash course in Fediverse. I was browsing stuff on Mastadon and voila! I found these communities on Mastadon but I wasn’t able to post anything, but I was however able to reply to stuff. I don’t know how this works. I won’t be reading it now, but I want to know more about Fediverse, so a book or documentary, something really detailed would help (just don’t send me a website please :')
Asking for learning resources about a subject is a support question? Hopefully nobody makes you a moderator in my lifetime.
