Is it possible to display content by a group of authors without using a group module? I like the group module, but it's much more complex and robust than what I need it for.
Synopsis: We need to build a page that will display blog posts by not one specific author but by a group of authors dynamically and preferably contextually. The authors will not have control over this page or interact with it in any way. There will be dozens of these groupings of authors. The page will also display a view block of biographies for the authors that can be linked to the author's Drupal profile.
