shelley kindly notified me that the comment forms were gone. a little investigation revealed that they weren't actually gone; they were just not showing up. too much time spent in further investigation led me to the conclusion that display:table was yet again to blame, and should not be used by mere CSS mortals like myself. however, i don't know how else to make pages with giant images look good, so i'm continuing to use it on a more limited basis. i'm sure i'll discover shortly that this is still breaking things, and give up on display:table altogether.
