I have added a few lines of behind-the-scenes code to the online grammar (HellenisticGreek.com) to force all pages to load securely (https rather than http). The site has been available on a secure server for some time now, but with these changes it will be impossible to load any pages insecurely.
For a few days, HellenisticGreek.com may show up in your browser as insecure. But that problem will resolve itself in a few days when the domain name registration is finished migrating to a new provider. Since there are no transactions to be completed on the site anyway, it will not be a problem.
