I thought some of you may like to read this if you did not read it over on their forum.

Project scientist And the challenge is over!
As well as being exceptionally productive (beyond my wildest dreams), the challenge was very exciting and I hope all of you had as much fun as I did!
We did a LOT of sieving over the last 10 days. It will take a bit of analysis to determine exactly how much, but suffice it to say that we're a lot closer to opening up GCW-LLR than we were 10 days ago. Three of the 14 bases are now sufficiently sieved for us to start LLR, and another 2 are close. That will let us concentrate subsequent sieving on the remaining 9 bases, so they will proceed at an accelerated pace.
The challenge cleanup now begins, and those who would like to help with the cleanup are welcome to do so.
Next month is our annual "Tour de Primes" challenge, which is purely for fun and is all about finding primes instead of credit or points.
Although the schedule is still somewhat tentative because we're not yet ready for the SoB DC, the next two challenges after Tour de Primes are specifically to help with the double check effort for SoB and PSP in March and April, respectively. As many of you are aware, both the original PSP and the original SoB projects have ceased operations, leaving PrimeGrid alone to continue both conjectures. Before proceeding forward, however, we want to insure that there have been no missed primes, so full double checks are being done of all old work. The PSP double check started a few months ago. The SoB double check will be starting soon.
The double check tasks for both projects are (for now) a lot shorter than the typical large tasks that normally run on those projects. These two challenges will therefore have substantially shorter tasks than you might expect on PSP and especially on SoB.
I hope you all come back for the PSP and SOB challenges. If we get the same type of particpation for the PSP challenge as we did for this last challenge, we might be able to complete two thirds of the double check during the challenge!!! (I don't have the same level of information about the SoB challenge yet.)
Happy New Year's everyone, and I hope I'll see you in February, March, and April!
