Hi Tbworld,
I have the javascript of Infolinks included in showthread template. So if you go to a thread page and do view source you should be able to see it (all the way at the bottom).
Also, I have INFOLINKS_ON and INFOLINKS_OFF included in the postbit_legacy template. That I don't see in the view source!!
Attaching here a view source (txt file) of one of the thread pages from my site.
PS: Thank you for the compliments about my site
