A Group license covers up to four sections, and represents a 25% discount. It also consolidates purchasing under a single individual, so other Section leaders don't ever have to worry about licensing. As with individual Section licensing, signing up for multiple years gives an additional discounts.
You can create a Group license by going to to “Account” | “Section Details / Payment”, where you will see there is now a “License Type” toggle. After you complete the purchase, you'll receive a license key by email that you can redeem with your other existing sections or with new sections. E.g., at the time you create a new section, you can enter the license key… and that the new section will be automatically added to your Group. Similarly, you can redeem a key on an existing section account, and that section will be added to your group.
Note, if you redeem a key on an already-licensed group, your Group's expiry date will be increased proportionally (i.e., you get additional credit for what you've already paid for). In other words, you don't lose anything by consolidating your existing Section accounts into a new Group license.
I've also added support for volume licensing for Areas or Councils. You can get a volume discount of 25%, 35% or even 50%, based on the size of the purchase. Contact firstname.lastname@example.org if you'd like to set this up.
