Create a New Workspace
Under the Workspaces Menu, select the 'New Workspace' link. This will open the Workspace Builder.
Select a Name for this Workspace as well as how you want it laid out. All of this can be modified later.
Your newly created Workspace is now ready to fill with content.
Next, select which Modules you would like to appear in each area. Simply click on the small arrow at the top right of any blank module and select the content you want in that area.
Continue to put in the modules of your choosing. Change them at anytime.
