Before users can click online training in their LMN menu and complete courses they will need to be registered. This must be done by an LMN user with security admin permission. If you are a security admin user you will see setup users in your main LMN menu as shown below.
Next you will see a list of the LMN users at your company. Click a user to bring up the edit user screen. Then click the online training tab to register that user for online training.
