It was basically a website where people would post the location and a brief description of a fit girl/boy.
It got shut down, the one that was all the rage at my uni did anyway.
It was creepy man, so for example, if there was a good looking girl in a particular computer cluster somebody would post "JRUL, B1 Comp Cluster by the printer, hot girl blonde hair nice legs" - or some shit like that...and then you can guess what would happen next lol...
This is what would happen :lol
There are ALWAYS lovelies in Blue 1.
Sounds troubling, though.
