Update, I figured out a workaround that does the trick nicely. Here's the code I used to achieve it:
[url=http://elliquiy.com/forums/index.php?topic=110474.20000#lastPost]Latest IC Post[/url]
Basically, what this code says is "go to elliquiy.com forums, find the topic with the assigned number (in my case "110474"), then go the page in that topic with the 20,000th post, and finally go to the last post on that page."
This will work for me a long time since the forums only show 25 posts per page and my game is only on page 2. If my game lasts long enough and there are enough posts to surpass 20,000 posts, then I would need to increase that number, but the chances of that are slim to none. Since there IS NO page with a 20,000th post, I'm assuming what's happening is that the forum automatically jumps to the page with the post count closest to that number as possible. So by setting the post count to a ridiculously high number (in this case 20,000) you can trick the code into dynamically linking to the last post in a thread.
YAY AND STUFF!!!!
