Just an FYI to our readers; due to the volume of spam that's actually getting through the filters (still!) I've turned on moderation for the comments.  Don't worry - we're still getting notifications on new comments, and we're still reading them.  They might just take a little longer to show up than you're used to.  We're sincerely sorry about that, but it's better than advertisements for sites of dubious merit polluting the information we're trying to share!
