I couldn't reproduce while I'm [fully] logged out, but when I was logged in, as in, with my account... I found it via that link.
EDIT: I'was logged in on one screen, and logged out in an older FireFox Screen. I think? So, when I logged into the newer xenforo/FireFox screen, I clicked the older screen to fetch the link...It wouldn't let me?
I'm using FireFox 7.0.1
EDIT: I was clicking the perma link on this post [that #11 link], but right now I can't reproduce, either.
