Thank you Shela,

The question about exposing e-mails for our owners is somewhat under control.
You do not find exposed addresses on our web for you to copy, but a "click here" to establish a form letter to the owner preaddressed as it pops up so you can contact that person.
It stops outsiders from running a complete list of copies in a short time. Each owner has to be looked up, and that is time consuming.
