Good luck on getting that call quickly (because otherwise you'll jump 6 feet in the air every time the phone rings, and that's hard on the leg muscles.) In the meantime, start lining up your PAFs (phone-a-friends.) If you know specific areas that frighten you more than others (i.e., pop culture, sports, or whatever, look first for people who are strong there, as well as in general knowledge. Or, holler, and you'll find folks here who will volunteer.
Also, if you have any questions about the show or this board, don't hesitate to ask. We like to blather.
