Another suggestion that you might want to take into consideration is that when people are viewing post history, if I click on the topic above the person's post (inside the post history) it will bring me back to the first post of the topic. Perhaps you can make it to where it brings the person to the actual post instead of the topic.
Both of these suggestions are done on Bungie.net and it makes the travel throughout the site a hell of a lot more user-friendly.
I've already suggested once before to have the ability to change the topic title if you edit the first post. Not sure how well that was taken...
But another was that if you edit a post, you go back to that post instead of the first post.
Those would also help us Mods a lot, because nuking a lot of spam gets really annoying if you have to keep remembering the same page number over and over agai...well...ok, maybe it's not that hard. But you get what I mean.
