yes, you can add many, so when you post, it posts to all of them from my understanding, which is what makes it censorship resistant.
I think for the file server you pick only one from the drop down. Don't think I can select multiple.
when you say servers, do you mean relays ?
I don't think that's what's meant. we are talking about the image upload files uploading to a server pretty sure there's a difference with the relays. but hey I am no dev.
oh, I see, I'm actually confused on that part. maybe the relays are channels through which data travels to servers ? not sure, I need to look into it 😅
