Picked up this one just recently ala the PrimeGrid Challenge we are working.
 
Any badge from this project means that you are willing to go way past Bigadv experiences (lots of time per WU and little points)!  Folding points are a "walk in the park" compared to working on this project.   

Nice one texinga +
Earned the Bronze badge from project Prime Sierpinski Problem (LLR) thanks to the PrimeGrid Challenge we are working as well. Do not think I will catch up until the very end though. That now makes 11 badges from PrimeGrid.

Wow!!!
 

Thanks guys.  I was on the cusp of Silver in PSP (via our Challenge) and this also just popped in...
 
PS: Bc, you are in a unique category with all those badges among those that work on PrimeGrid.  Not too many people have that kind of conteibution and my hat is off to you for that kind of dedication to the work.

Here are mine so far:

Nice collection of Primes there GB!! 

just picked up my silver PSP badge, as well....
you wanna talk about putting in work for a badge, check out the SOB tasks....  other than having to crunch a task for almost a week, chances are you will be waiting at least a month on a wingman....
Not the longest running tasks they offer, the Genefer tasks on the CPU run about just the same time, but why run that long of a CPU task when you can do it on a GPU?
