If you look at the URL in the address bar it will look something like this:
http://www.buzzerbeater.com/community/forum/read.aspx?thread=156727&m=1
The number at the end that I have put in bold represents the post number that is displayed first.
You could change that to 46 and it will show you the 46th post in the thread.
Your suggestion would make things better, but in the mean time you can do what I said above :)
