Subgroups
Groups.io supports subgroups. A subgroup is a group within another group. When viewing your group on the website, you can create a subgroup by clicking the 'Subgroup' tab on the left side. The email address of a subgroup is of the form [email protected].
Not too many, but maybe per product (BITx/uBITx/versions ?) and divided if needed for hardware and software
