Congrats you are a Super Admin. You have all the powers on your Tuleap instance. But be careful, huge power means huge responsabilities. You can do lot of things being a global administrator of a Tuleap platform. Three of them are managing users, projects and available tools.
One Tuleap platform can host dozens, hundreds and even thousands projects and people at the same place, wherever they are. Faster to maintain, easier to manage, the centralisation of people, workspaces and tools make IT people job better
