I've customized the loop to use a template tag from Co-authors Plus, but after I enabled the "cc_extended" option in the Creative Commons Configurator (which nicely has coauthor support), I see a duplicate display, as follows:
- Post title, etc
- Post Meta with vcard and coauthors_posts_links once (my customization)
- Post Content with coauthors_posts_links again! (??)
- CC License Block with extended info (including coauthors_posts_links, as desired)
No success debugging either the cc or the coauthors plugin so far...
