Cruelty- please email me your orphan sieve files. I'm not sure I will complete them, but I'll likely do at least a little work from them. Email is this handle at gmail.

I am unreserving k=137. This should be marked as reserved by David Broadhurst. From what I've found out he has notified Wilfrid Keller about his reservation last month.
He is also working on k=137137.

I'm sorry to hear about your sieving of k=137 in vain. David will tell you ranges he tested if you ask him, but he is not coordinating his efforts with us so there was no way to know. Also, currently there is nothing about his reservation on the Keller's page. If you sieved high enough, for example to n=3M, you can consider testing some higher ranges. But there are also meny other promising k's, and I'm sure you will hit your next mega-bit prime soon. So, don't despair, just keep on going!

Edit: Keller just updated his page, and k=137 is listed as checked all the way to n=1849260 (the prime was at n=1849238).

Cool!

BTW, would you be interested in k=281 ?
It's the only k<300 with no primes with more than 100k bits, the largest was at n=93850 and no more up to n=600k.

I was planning to investigate such numbers further as right now I am looking for a prime for k=151 (141 and 269 already done)

I'm reserving 109, 131, 211, 221, 233, 245, 263, 281, 283 and 299 for 600000<n<2M. Right now I only have some spare sieving resources but after finding k=151 prime I will be also able to LLR them
BTW: k=151 has been tested till n=700000, and I am still working on it

Cruelty,

I just marked on the stats page all 10 Ks you reserved on Oct. 1. Although they are all low to medium weight I'm afraid it's too many to run efficiently even on several machines at once. True, better unefficiently than not at all, but somebody else might be interested in trying some of them later...

Kosmaj,
I am already at p=0.5T so don't worry
Also, I think that k=141 and 269 should be marked as reserved by VBCurtis - as I have sent him the sieve files till n=2M.
