4847•2^3321063+1 is prime!
As some of you already figured out, we've found a prime for k=4847! As posted on http://www.seventeenorbust.com/news/ the prime was discovered at 10:50PM EST on October 15th by Richard Hassler, a long-time user who has been crunching SB since August 2003!

Hopefully those disappointed by the artificial slowdown that double checks have caused recently are pleased that it resulted in a new discovery so quickly.
We're working to correct the scoring system so that these tests are worth as much per amount of computation as larger ones. Until we do, keep in mind that although the scoring has temporarily decreased, the ease of finishing a test has gone up which does improve your chances of actually finding a prime.
As always, we'd like to thank our dedicated crunchers for all their efforts thus far.
