Smile Oops i did it again. (Prime found)

Hi,

i have some good news.

214519*2^1929114+1 is a probable prime.

I have done internal checks with PRP and LLR on two different PCs and it is still prime.
Already reported to primepages.
Status can be seen here:
http://primes.utm.edu/primes/page.php?id=76631

To make clear why the stats say 23 days since last prime here the story of this finding.
The prime was found on a linux machine in my office. This is the only machine that i could let run all through my holidays.
I left office on the 9th of december and today i had the first chance till then to get access to that machine. And i found the following:

[Sat Dec 10 04:50:55 2005]
214519*2^1929114+1 is a probable prime.

12 hours after i left office to go to holidays the prime was found and so the machine calculated k=214519 pairs that are not needed anymore for over 20 days.

@Citrix: You shouldn't have dropped your ranges. This one was in one of the ranges you originaly reserved and dropped later.

By the way did i already say:

Congrats, I am happy that it was found, irrespective of who found it.

Forgot to mention that this is the largest prime of 2006 so far, lets see who breaks our records.

Congrats to Lars and the PSP team for another semi-mega prime

321search aims to find something big for 2006 too

It'll be interesting to see how the teams table changes with your new prime...

Congrats Lars!
You were even a bit unlucky... as soon as you stepped out of the office the machine found you a prime! lol

Anyways, this calls for an update to the mainpage, more specifically this line:
"We have already found 11 large primes..."

I have updated
http://www.mersenneforum.org/showthread.php?t=2665

I am thinking of removing the main page, since it serves no purpose. I will redirect it to the forum. (Anyone up for designing me such a page?). I was hoping I could point it to the new server, once we get one.

Any thoughts?
