Thank you very much for that link. It was all explained very well. I understand it much better now.

However, I do need to create the passwords somehow. The .htaccess file I have would work, but naturally the password files are located in a different directory on our new server, and even then, they wouldn't really exist because I've never created them.

So how do I create the passwords and with no access to where the Apache server wants to store them??
