Jeff sent in an email detailing the contest over at MySpace where you can win VIP or otherwise nice seating at a NIN show near you. In brief, post a comment in the NIN profile indicating where you want to see the show, and where you live. Winners will be selected randomly for the various tour markets -- it's up to you to get there.
Complete rules are listed here. From the rules: Residents of the states of Florida and New York are not eligible to participate in the Sweepstakes. Only one entry per person or group is permitted. (Don't spam the profile, kids.) Good luck.
