When you attend the 2014 IAR Fall Conference & Expo in Chicago, be sure to use the event app on your smartphone frequently so you’re eligible to win the drawing for a $100 Amazon gift card.

Starting as soon as you download the event app — do it now! — and continuing through 12:30 p.m. Sept. 6, the app will tally when attendees evaluate sessions, participate in conversations and share photos on the app.  Depending on what activity you perform, you’ll get between one and three points each time. You’ll be able to check running totals on the “Leaderboard,” and see who’s in the Top 20 along the way.

Then, at 1 p.m. Sept. 6, each of the Top 20 will have their names placed in a prize drawing and one lucky person will be randomly selected as the winner. That person will receive the Amazon gift card shortly after the drawing. The winner must be present at the drawing or another name will be chosen.

Remember that you can earn points for commenting, answering a survey or posting a picture on the app. IAR staff members will not be eligible to win.
