We use Twitter for sending news. Discretion with Twitter is very high, because you can choose there: Only receive messages from people I know. Lik this you be on no mailing list without your permission. Twitter is ideal for this purpose, and stay spam free. Please register yourself there, you will like it when you are new. Out acount is: #emissionlabs
Why we did so: Classic mailing lists cannot be used anymore, because of free email acounts. These companies allow third (paying) parties to spam you, and do you 'a free favour' by blacklist the IP adress of somebody who uses his own mailing list.
