Suggestions for those attending the HRPT, as most of you know it's going to be in a condensed area. Use hemote and semote as much as you can vs regular emote if you think your actions would be 'lost in the crowd'. Not to say you can't emote, of course.
Also, the room(s) where this is happening will be set so that you do not go hungry/thirsty, to alleviate the need for people to eat/drink in such a crowded space.
