Meeting templates

I deleted the three default templates that were listed in the drop down menu for 'Select Template' on the Enter Meeting Information page.

I can still create new meetings without choosing a template; but I want to convert a meeting room to a template and need the default templates to do so.

'If you are a host, you can create a new meeting room template. To add a meeting room to the Shared Template folder, you must have manager permissions for the folder.'   Is the 'manager' the same as the primary contact for the account?

In my case, I no longer have a Shared Template folder. How do I restore the three default templates listed in the drop down menu for 'Select Template' on the Enter Meeting Information page?
