Where: The Yet to be Named CHAT ROOM 2.0 at Justin.TV:http://www.justin.tv/d20radio
When: Theoretically these are done on Sunday nights, but this often changes. Other common times are Sunday mornings or Tues. or Wed. evenings.
Best way to find out when the next 'cast is?: Keep an eye on the Order 66 forum. GM Chris or GM Dave will post a thread there, usually a day or 2 beforehand, with the planned date & time. Sometimes it may be on the same day. If there are delays or reschedules, either GM Chris or GM Dave will try to update that thread.
