Each paper must have a designated presenter. You may indicate which author is the designated presenter on the "Paper Information for Submission" Page.

It is preferred that one individual be a designated presenter for at most two works. We recognize there are circumstances where this might not be possible, else a good paper would have to be cancelled. The submission system will flag in advance those situations where a designated presenter is over the limit; then the program committee will decide what to do (and contact the authors if needed).

Designated presenters for parallel presentations not registered by June 3, 2009 will have their papers automatically removed from the program.
