JUst as an experiment, I went back to Decmember to this thread:

https://www.ubbcentral.com/forums/ubbthreads.php/ubb/showflat/Number/170575/page/17#Post170575

And I copied a random phrase exactly from this thread:

"have the link carry the date/time tag"

Then I Googled that phrase and got not results. I tried this on my site with all manner of random phrases from different posts made since the move and NONE of the phrases were returned in Google. Conclusion: Google is not indexing my site threads at all! Now we need to figure out why! If Google chnaged the way they spider, then they did it at the exact same time that I switched to T7.
