Classic mailing lists can not be used any more, because of free email acounts. These companies are marketing your personal data, by letting others spam you. News letters from third parties get blocked, they just say it is spam.
So for the future, we will use Twitter for sending news. Discretion with Twitter is very high, because you can choose there: Only receive messages from people I know. Also you can land on nobodies mailing list without your own permission. Twitter is ideal for this purpose, and stay spam free. Please register yourself there, you will like it when you are new.
