Reservations are associated to a Project, so first navigate to the Project page. The easiest way to do this is by clicking on the My Projects menu item on the right under My Member Tools. You should see a list of projects that looks like this.

If you are not a member of any Projects, that needs to be corrected before you will be able to reserve any equipment. Under Member Tools you should see *CREATE A PROJECT. Click on it and fill out the form about your project. If you need information about filling out the form click here.
*If you do not see CREATE A PROJECT, please complete the Report a Problem form at the bottom of the site.
Once you are on your Project's page, you will see an additional menu of tools on the right under My Project Tools.

This menu will list the types of content you can create for this Project. In addition to Reservations, many Projects allow Shows, Blogs, Events and Wikis.
Click Create Reservation to start the reservation process.
Enter the From date and To date for the Reservation
