Mailinglists offer the opportunity to send e-mails to groups of people (i.e. students or co-workers of a particular branch).
An overview of all mailinglists can be found here: https://lists.ufg.at/mailman/listinfo
Each list is maintained by the respective admins (e.g. adding new members, setting the permissions). The admins and access to the admin-dashboard can be found here: https://lists.ufg.at/mailman/admin
