The policy of Sanity Injection is that all readers are welcome to post their comments. I encourage discussion. You don’t need to “register” for anything, but you do need to provide a valid e-mail address which will not be published, but is needed for legal and liability reasons.
I reserve the right to delete any comments that are inappropriate, which I define as spam, excessive use of obscenity, virulent personal attacks, or anything that is incomprehensible or unrelated to the post or comment you’re commenting on. I hope I will rarely have to do this. I will not delete comments simply because I may disagree with the author! All viewpoints are welcome as long as you can express them in a civilized way. 🙂
