Specifically, can one create a document or page that's accessible with out a log in?
Obviously you need an account and be logged in in order to create anything... but...
I don't think you need to be logged in to view blog posts or other documents in a space. Try to see if you can view content, Py... blog there are attachments in some like this "You can't use Modelbuilder": When Instructors need to get smarter
But you should easily be able to solve that by examining any Space and looking for content in the Document category if you prefer not to use a blog.
All content is accessible without logging in unless it is in a members only, private, or secret group. Commenting or replying would require you to log in.
