I have added a self-signed SSL certificate to logging in and admin functions. Other aspects of the site can also be browsed using SSL by adding https to the beginning of the urls.

I will be tweaking this in the future to see how it works out.

Because this is a self-signed certificate you need to accept it for it to work properly. This is nothing to be concerned about.

The steps involved for Firefox are show below.  You will only have to do this once.
