OK ......here is the story on the newsletters ............the newsletters are region specific .....as an example, the UK Umusic office sends out letters only to UK email addresses ......the New Zealand office sends out letters to the New Zealand fans .....etc.
Often the content is specific to region.
That being said .........the official website is probably your best source about the latest news on Hayley ........plus whatever surfaces on our forum and HWI.
Probably not the response you wanted, but it is what it is .....
