Hi there,
Sometimes there are techy problems with the newsletters, which we have no control over. We've started a special thread which we'll try to regularly update with links to the newsletters:

In the meantime, can you give the following a try and let me know how you get on... (Newsletters are sent out on Mondays and Fridays).
When you are logged in, click on Edit Profile at the top of the page.
If the "Please contact me with updates on Total Film" box is checked, uncheck it and then click the "Update My Profile" button. Then go in again, check the updates box and click the "Update My Profile" button.
If the "Please contact me with updates on Total Film" box is unchecked, check it and then click the "Update My Profile" button.
