I have a copyleft / copyright question.
What is the copyright status of the *comments* on my blog?
I want to licence my posts as CC BY-SA. My comment form has never told people that their words will be republished under any specific licence.
I could put something on there now - but that wouldn't retrospectively apply to all the previous comments - nor to the WebMentions from the Fediverse.
So do I just say that comments are © their author?
