Due to the new GDPR regulations I've sent everyone on our mailing list an email asking them to let us know if they still want to receive our mailing list. (Because GDPR requires organizations to have logs of the consent being given.)
This also means that as of tomorrow I will be deleting all email addresses that I do not have consent for. So if you didn't send me a message, you will be removed from the mailing list. Of course I will be happy to add you back to the list whenever you send me an email. Just send the email to firstname.lastname@example.org.
