You can add additional portlets to your page by clicking on the Add Content link. This will bring up a Content Panel on your screen. Choose a portlet from the menu and add it to your page. If the Enterprise Admin portlet is not on your page, add it now. You will see that the portlet has been added to the bottom of your page. To change the portlet placement, click on the title bar of the portlet and drag it to where you like. You can also change the template for your page in the Content Panel. This will allow you to arrange your portlets in one, two or three columns as well as designate the width of the columns. Try to experiment with adding and arranging all the portlets that you would like on this page. There are quite a few portlets that come bundled with Liferay Portal, so be sure to review them.
