I read a book* this past weekend that had some interesting items in it which may be of some use to the organizers of this event.
Psychologist Arthur Aron devised a series of 36 questions to increase acquaintanceship and intimacy in relative strangers. The questions start relatively innocuously and increase in intensity. He devised the questions to get to what is considered the second and third tiers of acquaintanceship: personal concerns and identity claims. Not all of the questions were given in the book* I read, but may be somewhere on the net. Aron calls them the "sharing game." The professional text in which the "sharing game" is described is: Aron, A., Melinat, E., Aron, E. N., Vallone, R. D., & Bator, R. J. (1997). The experimental generation of interpersonal closeness: A procedure and some preliminary findings. Personality and Social Psychology Bulletin, 23, 363-377.
Also, in Snoop, Gosling touted the OCEAN method of identifying traits as one that is highly competitive (and pretty much preferred in the field now) to Myers-Briggs. A 120 question test utilizing this method should be available at drj.virtualave.net. More webpages with information on OCEAN (also known as the Big Five) is listed in Snoop's notes: http://darkwing.ugor...ay/bigfive.html and http://www.personal....criptions.html.
