How to become pope

Pope Benedict XVI retires at the end of the month, the first time a pope has resigned in about 600 years. So the job’s open. Do you qualify?

If I remember correctly, the last guy to become pope without being a cardinal or bishop was, depending on what country you’re from, Camerlengo Carlo Ventresca or Patrick McKenna from Italy or Northern Ireland. But he was a fictional character in a Dan Brown novel.
