k=139
Nuggetprime informed me that he doesn't have enough resources to continue his search of k=139 right now but he hopes he will be able to resume his search later this year.
I'll leave k=139 reserved for him for a while but if somebody wants to test it we can cancel his reservation. 
Carlos decided to release k=33 for the time being.

k=19 has been tested to 1M. There are no new primes, but I'm continuing with it.
The last time I posted residues was at 940K, so the attachment contains residues from 940K1M. 
Kosmaj, are you still working on k=83? If yes then [URL="http://primes.utm.edu/primes/page.php?id=81948"]this[/URL] looks like something personal...

k=49
Update:
LLR complete to 950k. No new primes. 
k=81
LLR at n=900k.
No new primes since last update. 
Please note that the search limits for k=19, 49, and 81 have not been updated on [url]http://www.15k.org/riesellist.htm[/url] , even though the page says that it has been updated on August 20th.

13 and 127 have hit 1.1M on LLR.
reserving 119 from 500k to 1M. Curtis 
k=251
k=251 tested to 700,000. Continuing.

k=141,151,199,269 done till n=600000.
"Only" 5 primes for k=199 found in this range :wink: I am releasing k=199, and continue testing 141,151 and 269 until I find a prime for each of these :flex: 
Okay, I updated [URL="http://www.15k.org/riesellist.htm"]the stats page[/URL] accordingly (The first update after more than 10 days because the ftp server was down.)
k=199 is now up for grabs! I'm afraid that for at least one of your remaining k's you will have to go into megabit exponents to find the next prime. But I know that's not a problem for you. :smile:
