In order to get the most out of the use of the Blog and the calendar, you will need to sign in to Google. David Miles described this in his comments on the very first post.
Logging into Google is as simple as entering your current email address (does not have to be gmail) create a password and that is it.
Once you can log into Google, you should be able to comment on the blog and see the Calendar. If you can not do one or the other, Email me directly from the email address you used to sign in and I will fix it.
