If you don't receive it within 24 hours, (shouldn't take more than hour in fact) check your spam folder. If it never turns up contact the editor at the above email address.
All that's needed is your email address, nothing else.It will not be passed on to any third party or used other than to send you the weekly newsletter or a direct message from the editor. You may unsubscribe whenever you wish and your email address wil be deleted from the email server.
Final note, if you enter the wrong email address, eg a spelling mistake, you won't get the confirmation! There are currently 19 email addresses awaiting confirmation 2 of which are @btinternet addresses but spelt imternet and interner. Check carefully. Subscribe
