Thanks. Can I ask why?
We ask for your first name so you can meet The Prof; another thing we're wrestling with, how to introduce that (non-standard) experience in a clear way...
Unfortunately there isn't an obvious affordance for this sort of interaction (that I've yet come across) - it looks like an email signup, when in fact it's more like 'play a game'...an interesting challenge...
It would be interesting to see if a vague 'what's your name' approach, rather than a specific direction with a stated outcome, wins in a split-test.
If I want to try it, I will put my email for free. And then you can sell me anything by email, in a future.
