Is the detail log still available?
And why you not attach the log file here too beside mersenneform?

I do note that 7,355+ is the 100th number factored by NFS@Home. I leaked the factorisation on the "Some questions" thread in the QPB subforum.

No problem about the leak. Work has kept me very busy as of late, so I've had little time to update this site beyond keeping work flowing. I didn't notice it was the 100th factorization myself until I finally had a chance to post it. I will post the log over at mersenneforum.org as usual. I don't post them here simply because I never intended to post them at all, but the interest in them at mersenneforum prompted me to start posting them there.
