I'm looking to create an app that has the potential to have hundreds of user groups. Each group is to only access their own content. Members of a group will all have the same permissions to maintain their content.
So, I am trying to figure out what would be the best setup. Just use Joomla's user group structure or to put all of the users into a single user group and then use Seblod to create some custom field to identify what content they can access? I've built a couple of Joomla sites, but they didn't need multiple user groups, so this is uncharted territory for me.
