Displaying a User Profile Field for the thread starter in threadbit

[msu2k]

On a forumdisplay page, specifically in the threadbit template, next to the username of the user who started the thread, I'd like to also show the contents of a User Profile Field for that user.

I know how to do it within postbit by using $post[field5]. How would I do the same thing in threadbit?

Here is the bit of code from threadbit...

<span style="cursor:pointer" onclick="window.open('member.php?$session[sessionurl]u=$thread[postuserid]', '_self')">$thread[postusername]</span>

If that's possible, how would I do the same thing next to the name of the last poster in the thread?
