My thoughts:

TMRL DRTG: Won't touch this one, too many ethical issues about helping hackers with cracking passwords.

PrimeGrid: I actually quite like PrimeGrid and will be crunching this one again soon to get myself some more Titan primes! I am more than willing to help out on this one.

RCN: I never could quite see the benefit to humanity by figuring out the least amount of lines that cross from X points. I'm not very inclined to work on this one, you can tell this from my points racked up.

SZTAKI: This project is on my list to build to 10,000 points.

Proteins@Home: Won't touch this until i start my build to 20,000 points or in a race. I quite liked this project.

VTU: Don't see the point in wasting cycles on test projects. If they annouced that they were planning to do something of use then of course i would contribute.

Xtrem Lab: I've never seen anything good happen to BOINC from this project. Exactly what is it that they are trying to achieve?
