@grayautumnday @obryanb Short answer: you need additional accounts on each server type.Long answer: Your account can post whatever your server is capable of. If your account is on a Mastodon server, it can post whatever Mastodon posts can do (so that's text with media attachments).These posts can be seen and displayed by other servers in whatever way the server is capable of, regardless of the server type the posts come from.
