New feature: New-post notification via email

You'll find a new checkbox in the Comments section of every game or event's webpage (such as this one), labeled Email me when someone posts a new comment about this event / game. If you check it, then whenever anyone (besides you) posts a new comment about that whatever-it-is, you'll get a copy of the full text mailed to you. Simple as that! Give it a try, and let me know what you think.

I also fixed a bug that was biting people answering invitations to some private events, only to be greeted by an ugly error message. There was some yucky cookie-based confusion in the works, but it's all cleaned out now. Thanks to CyberKnight for alerting me to it.
