In order to increase security, some browsers have begun to label websites that do not have a security certificate as 'not secure'. This site uses an SSL certificate to guarantee that it is the site that it claims to be. You may see an address containng ixsecure - this is the secure site that we use. You should continue to use the normal web addresses - they will automatically transfer to the secure site.
Please e-mail the webmaster if you have questions.
