Option to hide "Please Log In or Register" link

Hi,

It would be great if you could add an option to hide the “please log in or register” links.

I am using the support tickets in guest mode where visitors simply type in their email address to see their tickets. We don’t allow visitors to create accounts on our site.

Every time I update, I have to go in and un-comment it as it does cause confusion to our customers.

Thanks
