I found some primes, what should I do next?
I've done sieving and LLR'ing 15k=187466565 with n from 1 to 100000 and 100000 to 150000 is in progress and I've found some primes. There are many small primes, e.g. n={7,8,11...} as well as some bigger ones, up to ~27000 digits long.
So, what shold I do next? http://mersenneforum.org/showthread.php?t=640 says "submit them to http://primes.utm.edu/primes/submit.php", but how do I get the "prover id"? There are also "POST PRIMES you've found here..." and "Post small primes..." threads lying around What primes are considered "small"? Please, help me to sumbit primes and get credit for them as I'm very confused with all those instructions lying around here...

Length of k*b^n primes can be calculated as length=log10(b)*n+k. But keep searching!

EDIT: length=log10(b)*n+log10(k)=n*log10(b)+log10(k) of course. I should think twice before "submit" button...

There also exists http://15k.org/stats.htm  main 15k status page, where all primes found are listed. PS: Thanks for the formula!

The "prime data base in general" contains many primes found in the last 10 years or more, but only those that can make in the Top5000 now can be reported (except some special forms). Currently, the 5000th prime in the data base has 56600 digits so your prime has to have more. The limit changes with new submissions and can be checked here.
The smaller primes you can report to the Post small primes thread, and they will be later included in the 15k stats. Good luck!

Thanks, Kosmaj! That is exactly what I wanted to know.
I'll report primes I've found and will keep on searching!
