I just uploaded files in the 682-700k range sieved to 23T (!) by Bliss. The reduction in number of candidates per file is more than 18 in comparison to files sieved to 11T. He is still sieving from 680k but we'll move to 700k soon. I think we can reopen testing now.

Thanks a lot to BlisteringSheep for his help in sieving!
