Found on 2008 Sept. 5 at 08h26m UTC (noticed by me at 22h28m) using my AMD Athlon 64 X2 Dual Core Processor 6000+ (with 2 GB RAM).

Congrats! May it be the first of many.

Good deal. I was worried we weren't going to find any primes with the rally.

I'm estimating that we tested ~30000 k/n pairs with the rally so would have expected ~5 primes. Finding 2 is not extremely unusual but finding zero WOULD have been!

Regardless, we knocked out quite a large chunk of work. Thanks to everyone who contributed!

The participation was better than I expected on such a short notice.

I moved the discussion on the issue that we had on port 7000 to a thread called 'port 7000 issue'.

Reminder to self: No header line need be sent after the first time a server is loaded. lol
