My site includes some guest authors that don't yet have posts, but I would like them still to have profile pages.
1. I've already successfully redirected the 404 page to use the author page template in the event that the query was for an author.
2. I've extracted (from the query) the taxonomy term ID and slug of the co-author sought. This may not have been the most direct way to go about getting that information, but I have it.
What I can't figure out is how to use the term ID or slug to pull a guest author's Co-Authors info, at the very least their display name and email. Do you have any advice?
