The World Beer Cup takes place in Philadelphia, PA in early May, and is seeking volunteers for the three day event.

If you have questions or concerns, the best way to contact me is directly via email, which can found at the link above. I'll try to monitor this thread as well.
(Please note, judges are industry personnel already selected by the Brewers Association, but BJCP points will be awarded for steward and staff positions.)
