I'd like to declare that I've fixed the "jump-to-first-unread-post" mechanic for forum threads. Bugs quashed:

1. It would jump to an offset only showing you the first unread post at the bottom, requiring you to go to the next page to read the rest. Now, it shows you as many unread posts as possible—without overshooting the first unread post.

2. Even if you'd never read the first post in a thread, it would jump to the first reply. Now it knows about the original post!
