A first-asked first-served basis will be used to solve any conflicts.
In other words, if two people want to lead the discussion on the same
paper, the one that has asked for it first will get it.
If two people are scheduled to lead the discussion on the same day, then
they have to choose the same paper (only one should send email).
Note that a lot of these papers are the draft versions of papers
accepted to upcoming conferences. Hopefully, we will be able to have
the final versions before the discussion.
