I think they air on Saturdays, should be listed on their Show Info page on the left side of wcradio.com ;p I'm not too fond of thm now...only listened cuz I heard every other show's archives already, I get more enjoyment out of Vendor Trash and Max Speed lol

Either email 'em before/during the show, or hop on their IRC(I forget the address but it's #wowradio on their own network, not sure if it's still irc.wowradio or not, but they have a java chat link somewhere on the site lol) and PM to whoever they say is taking the questions/comments, usually Emtee.
