Hi all,

As a co-admin of the No Prime Left Behind project, I would like to extend an invitation to all the members of Free-DC to come on over and check us out! We are a project searching for large prime numbers (as the name implies) of the form k*2^n-1, specifically for values of k from 300-1001. All of our search ranges are such that if you find a prime with us, it will make the 5000 Largest Known Primes list (essentially the Guinness Book of World Records of prime searching)!

Both manual and network clients are available, and we have a stats page where scores are kept for both types of clients. We also do an LLRnet rally every few weeks or so, where, for 24 hours straight (we hope to possibly do a 48 hour one sometime in the future), everybody participating in the rally will throw as much raw crunching power at one of our LLRnet servers, with the goal of finding as many primes as possible and pushing up our searched range higher at the same time. They're a whole lot of fun, and provide excellent opportunity for team rivalry!

Currently Free-DC is in the lead in the NPLB stats, though their presence there has been waning of late, and the "no team" team is catching up on them fast! So, I challenge all the Free-DC members to make lots of big on NPLB to secure their first place spot!

We also have a sister project, Conjectures 'R Us, for which the goal is to prove all the unproven Riesel and Sierpinski conjectures for bases <32, and even higher for bases that are powers of 2! Like NPLB, Conjectures 'R Us has both manual and network clients available, and though it is a smaller project, it's still a lot of fun. So, if proving mathematical conjectures is more your thing, you've found the right place.

Come check us out!
