I know I'm responding a little late to your post, but I just want to say that counting a post written on page 249 of a thread is megacrazyuber generous on your part. Shoot, I've always thought if a thread goes on for longer than 15 or so pages, nobody's really doing much reading in it. Come to think of it, I've always had the suspicion that there's about a 50-to-1 ratio of posting:reading behavior on average, no matter how long a thread goes on for. That might not affect visibility of a campaign's signature and avatar necessarily, but who knows.
Is it bedtime yet??
