This mailing list is announce-only.
First, we don't share our mailing list with anyone, that's a horrible idea. Secondly, all our subscribers subscribe themselves, we don't add anyone to our list, without them going through a confirmation process. Lastly, you can leave at anytime - it's easy to do.
