The thread imploded here in post #3 . Yes, I can see plenty of reasons why someone may not want to explain every last detail of their search for information. But nobody was asking for that. Just a little added context (even less than the OP provided later) would have been sufficient to make anyone willing to share information. But this rude reply isn't going to make anyone want to help. It was so prickly that I thought maybe it was a non-native language issue, but later posts make me doubt that.
