From Stinque Zombie Bible
We have better things to do than spam you.
But if you'd like the details, we require confirmed email registration to edit the Zombie Bible. This helps us keep the riffraff out (or in, depending on your perspective). It also helps us reach you in the unforeseen event we need to talk to you about something. ("Unforeseen" here means: We have no idea why we would want to talk to you.)
We don't have a mailing list for contributors, and if we ever do, we'll make it opt-in. We've also turned off user-to-user email, a common feature with other wikis.
You may receive automated email from the server, like the message used to confirm your address. Most of those we're switching off, in the interest of computing efficiency.
In short: We really don't care who you are, we don't want to know, and we don't want anyone else to know. But if something reaches you that shouldn't, give us a holler at firstname.lastname@example.org. It was probably an oversight on our part, and we'll fix it.
