Cookies and a valid email address are required. You won't be able to comment without them. Allowed XHTML tags are shown beneath the comment box.
As far as content: almost anything goes. Approximate 500 word limit (2,500 chars). Threats will not be tolerated unless they are very, very funny.
The first time you comment here, your information is saved and you are given a cookie on your computer with a key to retrieve it. If you have cookies enabled, you should only have to enter your information once.
The first time you comment, you will be mailed a comment confirmation link. Click on it within 5 minutes for your comment to go up. Future comments may be entered without confirmation unless you change your information: email or name. If you do, we'll send another confirmation email to make sure it's still you.
This prevents comment spam and enforces honesty because you must give your real email address to participate. It also means you don't need a password because your ability to answer your email address is your proof of identity. It is not shown or linked on the site. We never have and never will sell or share your information, or send you unsolicited email.
