South African cardinal Wilfrid Napier, who answers all tweets at his @CardinalNapier, entertains his more than 5,000 followers describing the pre-conclave atmosphere.
"We chat, discuss, get to know each other. Meals are special times. We relax, share stories about our home Churches, dream about the future," he tweeted.
As for the conclave, whose date has not yet been set, Napier wrote: "What's it like in Conclave? Apart from NO radio or TV, NO newspapers or phone calls, Emails or SMS's, NO Twitter or Facebook, all is normal."

Other cardinals such as the French Jean-Louis Tauran and the Italian Tarcisio Bertone, have preferred to suspend their accounts until the election of the new pope.
More drastically, Cardinal Angelo Scola from Italy, another of the bookmakers' favorites, shut his account, amid speculations that he will soon use the @pontifex account, suspended after Benedict XVI's resignation.
It is unlikely that the Pope emeritus opens a new account. This weekend, Benedict has been photographed as he walked around the gardens of his retreat near Rome, wearing a white baseball cap and a white jacket, just like any old retiree.
