If you attended the IMS2012 show in Montreal, Canada, your name and contact info was just provided to all the exhibitors "for verification purposes" - whatever that means. Maybe if you read the fine print in the registration form it warned that your info might be provided to 3rd parties. Regardless, it's out there. I have no idea whether your info is also being sold or given away to other entities. So, if you start getting a barrage of e-mail and snail mail solicitations soon, this might help explain it.
This is an excerpt from the e-mail sent to exhibitors at the end of the show:
"All IMS2012 exhibitors receive an alphabetical listing of this year’s Conference and Exhibit-Only registrants. The list includes the name and address of all 4427 registered attendees and is sorted in alphabetical order by last (family) name. To download the list click here. The listing is provided without charge and is intended for verification purposes. Also included are the demographics of the conference detailing the breakdown of attendee types and aggregate data as reported from the conference registration form."
