World Record Factorial Prime Found
From http://www.primegrid.com/forum_thread.php?id=1336:
A remarkable discovery was made yesterday in PrimeGrid's PRPNet. Dmitry Domanov found a World Record Factorial prime. 94550!1 is prime and is 429,390 digits long. It enters Chris Caldwell's The Largest Known Primes Database ranked 1st for Factorial primes and 155th overall. This is only the 24th known Factorial prime...the 14th discovery in the last 29 years and the first in almost 8 years. Needless to say, this is a very rare find. It more than triples the size of the previous record of 34790!1 (142891 digits).

Could this be the biggest prime yet that uses general modular reduction? It's going to take several hours for The Prime Pages to confirm it's a prime Last fiddled with by paulunderwood on 20101005 at 22:03

Without using special modular reduction  it is general.

If GIMPS also found a prime, you'll have to add that to your list
