You can create a new area by using the
Add An Area command. This command is available from your home page by clicking on the add icon (
depicted below).

Selecting this command will display the Add An Area Dialog which is used to select the type of area that you want to create.

This image shows the Free area templates that are available to all Organize Us members. If you have a premium account, you will have access to additional templates.
Once you have selected a new area template, select the create button to create your new area. You will be added as an organizer of the new area so that you can then configure the area the way that you want and invite other members to join the area with you.
