1) Documentation (Book Pages) from Blogs
This is standard drupal feature that is great for pulling book nodes from blog contributions. It would be great if this could be enabled in OA. I am envisaging a contributor posting a procedure or set of reference links that could be quickly cloned into a book page by a group manager.
2) Taxonomy menus or tag clouds for groups.
Once a group becomes populated, it will quickly become difficult to find content relating to particular topics. I know we could search, but a taxonomy summary view or cloud fo each group would rock. It would be significantly more useful than a pointless graph of group hits.
Awesome work guys...
