my screen is just clogged up with gazillions of posts about keeping yer shoes on in the house, like i care...
much as i like the fact that recently added-to threads bounce back up again, imo you are showing too many of the messages.
can't you just do the last three messages or somesuch and then have a button to take you to the last unread post? for people who are on more than a couple of threads, it's all too much like hard work to scroooooooooooooll down through so many posts. moan, chiz, moan etc.
