- Grouper
Anyone needing to manage group access to resources can use Grouper – from accountants to zoologists. A researcher might create a group and enable members to participate on an email list or view a web site. Students might use Grouper to set up and manage groups for similar applications as they work together on shared projects and class work. Your IT staff can delegate group management and enable those leading collaborations to set up and manage their own groups. - Permis
