Update
As it turns out, I got the itch to work on the links to individual posts. That feature was not in place before this morning. I finished working on that just now and am heading out to lunch.
The link at the top-right of each post that shows the post number will now properly route to that post. It shouldn't matter how many posts per page a user displays either, they should be taken to the correct post regardless. Old links to specific posts will also work once the domain name is transferred over.
This means that the section summaries and search result summaries will also link properly to the last post of the thread. Maybe you never used it, but I use that feature a bunch. You'll recognize it by this image:
We'll see what I tackle next...
