We could have easily used 40 tables for placement. Some universities kindly shared tables, others found tables smattered throughout the convention center, others opted to interview from their hotel rooms. Thanks to all people who graciously adapted to the resources, but again I strongly recommend more 4-top tables. The message box did not work. I think the boxes were too innocuous to warrant trust.
People like to post big messages on a widely visible board.
I didn't need technology onsite as only 5 people registered for placement at the conference, and it was easy to direct them to the PC room to register online. He and I were only both needed the morning of the first day of the conference. After that, we traded off so we could both attend some sessions. She invoiced AIS and ICIS herself.
