I'm probably going to use Acquia Commons to put together a site for communities, and I understand that it's set up as installed to have administrators create the groups and subgroups. However, I'd like users to be able to petition for new groups (and subgroups?) to be created in a process something like Stack Exchange's own Area 51, though perhaps without the following phase.
How would I go about implementing that sort of thing on the current release of Commons? It's based on Drupal 6 until more modules are ported to D7.
