When you click the "mark all topics read" button, you wait, then get the "topics marked" screen, then wait, then go to the forum you marked. This last seems silly: if you've just marked it all as read, you probably don't intend to keep reading it. I know it's just one click, but sometimes it takes quite a while to bring up the screens and whatnot. I'm wondering, could it dump you to the General Forums board instead? If this is in any way complicated, please don't bother; it's just a slight efficiency thing after all.
Thanks!
