Well someone suggested looking at the forums, so I was poking around the sourcecode. Found something that stood out to me, but havent been able to make an actual code out of it... maybe someone else will come up with something from it.
There are eight links on the page which have a single digit 'accesscode' on them. In order of appearance they would be s5323419
I can't see any reason why the links would need this variable. The variable isn't unique either since there are two number 3's. Since the first one is an s, this means that its not just numbers, but alphanumeric.
Also, the links themselves vary - they're not all the same type of weblink. ie: one is a javascript.
Since it's the forums, I don't know if the line I have listed them on will always be the same or not, so I'll paste the lines below as well.
Code:
line 104 <input type="submit" class="loginbutton" tabindex="104" value="Log in" accesskey="s" />
