We have found that most zencart users do know how to FTP, but other ecommerce platform users don't. However, occasionally a zencart site owner had a dev/designer do all the work, and all they know is how to process orders. Then I have to explain what to do.

Shoot I even have had to explain what a computer desktop is before to a website owner.

Thanks I guess this thread can be closed, with there is no way to edit the head inside of zencart's admin panel.
