You also consider that the creation of automatic groups by users can be deleterious.
You could have dozens of groups dealing with the same theme that have a similar name.
Paradoxically, your users could create:
- Audi Australia
- Australia Audi
- Audi Australia group
- Australia Audi group
- and so on…
before realizing that there is already an Audi Australia group. Or worse, a user could join the group, find users he does not like and create an Australia Audi group etc…
The simplest thing instead is:
- create the Audi Australia group
- make the group visible to everyone
- configure the group so that users can enter and exit freely
- giving “create see reply” permissions only to group Audi Australia in category Audi Australia
In this way every user can self-manage himself.
