There was a place in Helper Resources at the bottom, where possible Duplicates were listed.
It is no longer there. Can I find it somewhere else?
I still see Possible Duplicates at the very bottom. Perhaps the person you are looking at doesn't happen to have any possible duplicates. It makes sense that that section would be omitted entirely if no one fits that criterion.
The area I was referring to came back on, so maybe the engineers were working on it.
