After the first round (or two) one can also use tournament experience to post “no sooner than” announcements, letting people know if they want to leave for a set amount of time, they can.
I have a few thoughts for the chief td in this event, who does seem to have been directing tournaments at least since 1992. The first of these thoughts is THANK YOU for bring US Chess to so many youngsters in the New Mexico area for over 26 years !! There is a major reason why our federation is filled with holes of inactivity, with few US Chess opportunities for untold thousands of youngsters - a lack of adults willing to organize,and become US Chess certified tournament directors in these near void areas.
Further, I do agree with at least several who have so stated, that truly the best approach is this. Input from the organizer is needed before further adequate discussion, should he care to comment, which I am in no way suggesting he should.
