To create a new project, do the following:
Press the 
button located in the Shortcut bar in Project mode. The Project property sheet is displayed showing the Details page. Enter a description for the project. You may also
select an owner for the project from the drop down list of users. The drop down list contains only those users to whom you have at least create general access.
Select the Access tab. From here you can specify the access rights that each user has to the project. By default, the project is marked as personal which means that all users that have access to you will have the same access to this project. For further information on granting access rights, see Administering Access Rights.
When you have specified the project's description and have granted the relevant access rights, press OK on the Project property sheet. The new project will be created and will be automatically opened, ready for you to start adding project tasks.
