To change your default system module, click on your name, which is always displayed in the top right hand corner of the screen.
The 'user settings' popup will then appear. Click on ‘Advanced Settings’ tab, and additional options will then be displayed.
Against the label ‘default module’, you can select from the available selection of modules which you subscribe to.
Once complete, press ‘save’. The next time you log into the system, you will be taken directly to your new module.
