The hashed emails of the authors are in the dataset. We have a list with 
contact information for all attendees but I doubt that it would be OK to put 
it on the web due to privacy reasons. I will check with Sean.

It is exactly that kind of data merging and mining that you plan to do which 
is great on the one hand but could also get very intrusive in the future if 
people not only do it for honest reasons.

So, lots of interesting questions here ;-)

Cheers

Chris
