The Sierpinski/Riesel Base 5 project needs to find four more primes to make this the best year in the project. To see the number of primes found by year, look at the Primes Reported paragraph of the Description post. http://www.mersenneforum.org/showthread.php?t=14060 This is also a good place to find out more about the project.
Using prime scoring, the years shape up like this:

2006 9319511 2010 8390964 2007 4763138 2005 3401124 2008 1907691 2004 436873

Unfortunately, PG's PRPNet does not support SR5's PRPNet v2.4.7. However, if anyone is interested in helping them make 2010 the best year so far in regards to prime score, you can participate through PST's server by adding the following line to your master_prpclient.ini file and updating:

server=sr5:100:1:prime2u.com:7171

Year Score
2006 9319511

SR5 Project Description
This project is an extension of the original Sierpinski/Riesel problems. It is attempting to solve the Sierpinski/Riesel problems for base 5 by determining the smallest Sierpinski/Riesel base 5 numbers. Therefore, primes of the form k*5^n+/-1 are being sought for even k's.

For more details, please see their project description.
