Referencing original thread URL from vBCMS Article

[cash7c3]

Real example:

http://modmyi.com/content/16967-appl...est-rates.html is an article page.

It's original thread is http://modmyi.com/forums/mac-news/84...est-rates.html

In the THREAD header, I would like this code:

<link rel="canonical" href="http://modmyi.com/content/16967-apple-set-issue-bonds-euros-due-low-interest-rates.html"/>

I am not terribly opposed to it being the other way around, but prefer the canonical link to be the article URL.

I do not know how to do that, and am hoping someone can assist. I don't know how to do a query to get the article id, nor what to do with it when I get it.
