A reader very kindly let Dr No know that the email subscription form (“Subscribe to Dr No” form on the right) was broken. There have also been some odd random ‘unsubscribe’ events for subscribers where Dr No knows the subscriber didn’t unsubscribe (because the subscriber was a test email address used by Dr No!). Dr No has therefore migrated all subscribers across to a new system which appears to be working (though you never can tell 100% with these things).
Existing subscribers should not need to do anything. They should already on the new subscription list (and should get an email notification of this post, which will confirm they are on the list, and it is working as it should).
If you thought you were subscribed, but don’t get any email notifications, please let Dr No know via the contact form, and he will do his best to sort things out.
New subscribers should now be able to use the form on the right to subscribe. It has a double opt-in to prevent bots subscribing (you get sent an email, and click on a link in the email to confirm your subscription). Once you have done that, you should get sent a notification email every time Dr No posts a new post.
Dr No apologises for all this fuss, especially to those who have tried to subscribe, only to be frustrated.
