This is a GNFS target, so I need to allow time for ECM and polynomial selection while sieving the last 2 I reserved.

It's a GNFS job, so needs time for ECM and poly selection before I start sieving.

Poly selection for 480393499^23-1 probably won't complete before I've finished sieving 934415109937^19-1 so I'll have to pick something else to do while poly selection continues.

Reserving 10378063^37-1 to do by GNFS (after ECM).

This is the last number in i_51_2000_101.txt that's in my range.

I noticed an update to the Most Wanted Road Block file was posted 12/2014. I completed about a dozen easy ones but the file has been gone for a couple days. Does anyone know if a new update is in the works?
