I see that I can comment on a post from an external account, and I also see that I can even make an external account a moderator in a community I administer. The question is, how can an external account create a post in a community it is subscribed to? Does that account have to create an account in the lemmy instance and login first?
On Friendica, all you need is to !-mention the community where you want your post to appear
I see. Good to know.
