Some followers of this Blog have put their email addresses into the "widget" on the right hand side of the main page. This means you get a notification each time I post something new and it saves you checking the Blog unnecessarily. Google is planning to introduce a new interface at the end of this month and a lot of things seem messed up at the moment. I am aware that the email notification has not been working for the last couple of posts. This may be a temporary blip but if it persists you could try putting in your email address afresh. Sorry for any inconvenience!
