Wiki radius howto - missing link problem

Hello, I didn’t know where to put this, so I posted my question here.

I am developing a Freeradius/MySql/ROS accounting system for our own needs, and I am following instructions from

http://wiki.mikrotik.com/wiki/RouterOs_MySql_Freeradius page.

At the end of the page, writer posted a link with way to use MRTG for traffic graphing for each individual user, but this link is dead. I googled the item, but all links related to that one are dead.

So, I am asking if anyone out there has saved that link , can you be so kind to put it up somewhere accessible ?
