We will soon be reopening Primorial sieving after I hear from everyone who was sieving it 2+ years ago. The reservation thread will be on PST rather than on PrimeGrid itself. It's far easier to administer there as the tools available to a moderator are much better there.

I'm still waiting to hear back from five people who did a lot of sieving back then. If they still have the old files then obviously those ranges won't need to be redone. I expect to reopen sieving in the next week or so.

Factorial sieving is probably in a similar position, but I haven't gone through it file-by-file yet. It'll also be moved to PST after I determine what's missing.

Hopefully we can get a decent amount of sieving done to eliminate a decent amount of canidates for the Primoral prpnet challenge in December.
