notice of procedural change

i originally set the comments so that you had to sign in to leave one, because i had heard so many tales of spam woe. but then another blogger who wishes to remain anonymous told me that she's never made people sign in and she's never been bothered by spam, so i changed the setting: you can now comment without signing in. so if you were holding off on commenting because you didn't want to deal with signing in, fire away. if you never wanted to comment anyway, well, as you were.
