The 115 eligible cardinals gathered in the Vatican are the only people on earth who can pick the next pope — and they vote today on when to start their conclave to do just that. But you can help, indirectly, if you have an email address and a few prayers to spare. On Friday, the Vatican gave its official blessing to Adopt a Cardinal, a website launched by Germany-based Catholic youth organization Jugend 2000 (Youth 2000).

Here's how it works: You enter your name and email address in the "adopt" section of the site, and Adopt a Cardinal sends you the name and information about a randomly selected cardinal-elector, "who you will support through your prayer and intercession during the coming weeks before and during the conclave and for three days following the election." The cardinals know they are being adopted: They were told about the website in their gathering Friday morning, where they also talked about a whole host of issues the next pope will have to face. Picking a new pope is generally seen as the most important thing most of these princes of the church will ever do. "The cardinals need to be prayed for," said Ulli Heckl, 37, one of the Germans who created the website.

As of Friday morning, more than 360,000 people have adopted one of the cardinals.

If adopting a cardinal elector is not your thing, there are other, less "reverent" interactive papal-selection tools, says Bill Ward at the Minneapolis Star Tribune. "Ever since Pope Benedict proclaimed that he was to become the Holy See You Later, speculation has been rampant as to who would replace him," and the gambling sites have rushed in — "Ghana's Cardinal Peter Turkson is the current favorite at 5-2." But there are also less sinful sporting-style prognostication sites.

One is called Fantasy Conclave: "It's like fantasy baseball, except these Cardinals are not from St. Louis," says Ward. It is not, surprisingly, "the brainchild of an iconoclast." Fantasy Conclave is the work of "eCatholic Evangelist" Michael Marchand, and he fashioned it to educate and entertain; each day, players get emails about popes and the elaborate papal selection process.

"Slightly more catholic (in the lowercase sense) is Pope Madness 2013," Ward says, an NCAA basketball–type bracket systems with "reverent round names" — Sweet Sistine, Ecumenical Eight, Flagellant Four, and Diocese Duo. And it does have "regionals that actually live up to their names (South American, Italian, etc.)." Religion News Service has a similar Sweet Sistine bracket game.

The only contest with a prize, though, is Fantasy Conclave, which is offering up swag from sponsors, including a $100 gift card, Catholicism DVD series and study guides, autographed copies of Catholic books and a life-size cutout of Pope Benedict. [Star Tribune]
