Folks, I believe that this thread was started by Gwen to find a date for the next Chicago Gameday. However, a date has already been set: June 12th.
Gwen, this was announced in the current sign-up thread, and was sent out to the mailing list (of which you are a part).
So, I repeat, this is not an "official" thread for ENWorld Chicago Gameday. This poll will have no effect on planning for the next event.
