Finding the userid has never been tougher

[bo0oost]

At least for me! Can anyone help?

I need to find the userid of the last poster in a thread.

For example on this page, forumdisplay.php:

https://vborg.vbsupport.ru/forumdisplay.php?f=111

if you look on the right hand side, it shows the user that posted last in that thread. Instead of it linking to the lastposer, and going to the memberpage, I just want a direct link right into the memberpage.

I'm trying to modify threadbits template, but any userid variable I try doesn't work. Anyone know how I can get the userid variable for the lastposter there, so i can just do a direct link into the member page?

Trying to do this so there are not two different URLs going to the same page (for SEO).

Thanks for your help!
