I'm sure they will be formulating the judge assignments in the next few weeks. I expect that we will hear something a week or so beforehand.
It would be quite nice if notice was received more than a week in advance. If I'm not judging on Thursday I'd like to know sooner than later, so that I can fill the day with other things beery.
I'm not sure that we will have everything nailed down too much more than a week in advance. But we will get assignments out at least a few days ahead of time. This will also let you know if you are not needed to judge and are free to drink in all that Philly has to offer.
