Uli is unavailable to run the Tour de primes, but amongst all the challenges we run on both PRPNet and BOINC, the TDP is the only one that's exactly the same each year, and the only one for which there are special badges awarded.
Given this elevated status of TDP, we're looking into running TDP on our own. Nothing is finalized yet, but there's a possibility it will start on February 1st as usual. More information will be forthcoming once I know more.
