As an administator, a global content manager or user manager (or with such permissions locally delegated for that training, see User roles for more details) you will be able to manage the training's settings.
To do that, you will have to click on the "pencil" pictogram at the top right side of the training's homepage, close to the start button.
The edition interface is the same as the creation interface, please refer to Create a training page for more details.
Admin view of list of trainings
As an administrator or a content manager, you can access from the administration menu an interface that lists the trainings, by clicking on "Manage groups" item:
From this interface, you have the possibility to add a new group (course or training), to search for a precise training (according to its name), and to sort the list by name or owner (user who created the training):
By clicking on the wheel pictogram on the right side of a training, you can either edit it, duplicate it or delete it. Duplicating a training will create a new training with the same contents inside (courses, trainings, documents) but with an empty list of users. Live meetings, instructor-led sessions, forum and collaborative workspaces won't be duplicated since it's specific to a precise training and the related users.
