Did you see the talk from the guy doing mdma research for trauma? I spoke to him after his talk on the level below the main stage entrance, to the left as you are walking into the building (on the chairs sorta by the breakout session rooms). He didn't want to talk to me either. I was asking questions about his study and I hadn't yet even told him about where I thought it wasn't robust enough in the study tools. Even though that's sorta what I do for a living. He was in a hurry to have his phone checked for spyware or meet someone else or whatever.
