I included most of this in the “Terms and Conditions” page, but it bears repeating:
Sign up using your real name and email, if for any reason we need to get in touch with you, we will use this address. We will not contact you directly except if there are issues with your account that require your attention.
We will not otherwise send you unsolicited emails, or provide your contact information to anyone else. At some point we may add a newsletter, but you would have to subscribe on your own. We would not send it to you directly without your permission.
