We are a non-profit transition movement in Norway. If we as ha "head office" sign up for a user license, will all our grasrootgroups (=neigbourhood) around in Norway be able to use the same license?
First of all welcome to CiviCRM :)
As CiviCRM is published under the free GNU AGPL license there are no licensing costs and you do not even have to sign up. All your grasrootgroups can use your database or get their own copy /environment of CiviCRM (depending on your use case / requirements).
