To add a new skillgroup to your implementation simply select the "Add a New Usergroup" button located on the bottom of the "Usergroup Search" sub-tab page of the Usergroup component.
You will then be brought to the "Add a New Skillgroup" sub-tab page. To complete the process, simply enter values for your new skillgroup in the available fields and click on the "Apply Changes" button. You can refresh the page to reflect any un-applied changes by selecting the "Refresh" button or cancel any un-applied changes and return to the "Skillgroup Search" sub-tab page by selecting the "Cancel" button.
