Hello, I'm investigating about the Organic Groups feature. It looks very useful, but I really think I will need to create not only groups but subgroups. Sadly, the subgroups module is not stable for Drupal 6: http://drupal.org/project/og_subgroups Worse, it looks like the last time this module was updated was in 2008! I don't know a lot about OGs. Is there a way to create subgroups in Drupal 6? My customers are schools. I want to make an OG for each school, so all the students are registered with their school, and I want to allow teachers to create sub-groups to represent school classes. I figure that this would make it easier for teachers (and for me) to manage all the students (e.g. to check their work). Does anyone have any suggestions for me? Daniel.
