[Plugin: SF Author Url Control] Does not update get_author_posts_url

Hi.

That’s strange, I’ve just try it and it works perfectly for me:
get_author_posts_url( get_the_author_meta( ‘ID’ ) )

It would also be helpful to indicate an actual page to display for the slug for all the authors.

You mean an administration page where you can see all the author slugs?
Simply go to the “Users” page, a column is displaying them (the ones that have been modified are green).
