I only see this working if there are multiple posters for each conference. As jhawk stated above, I don't think there are many if any posters within my conference of interest, but I do enjoy seeing other discussions with other conferences and on this forum. Also, as EastIowaHawk said, two posters would have to be the minimum, because one person may not know everything going on within the conference that night to keep everyone updated, and at least two can keep a discussion going. That's just my point of view!
