i don't know where to find userque. perhaps the more pertinent question is why do you want to find userque? but he better be keeping track of trades posted in case he ever gets that duct tape ripped off his mouth and can speak again.
that being said, if a person was looking they might start by asking siri the apple artificial intelligence gal with the sweet vioce for his location, but be careful she likes to trick folks.
otherwise i guess one would start by searching the google for nueral networks, but be prepared to be led deep into the matrix down that route. follow the white rabbit. and always take the red pill.
