New Subprojects
The real question as I would imagine is: can someone post primes that do not fit into one of the three subprojects defined on RPS project page?
Another, similar question: can we extend the list of subprojects? Some candidates that come to my mind include:  Gaussian Mersenne Norms and conorms (PRPs)  highweight "k" proth primes (as suggested by Roger)  some other ideas developed by participating individuals (e.g. I am working right now on primes of the form "4*3^n1")

I think we can indeed extend the list of subprojects to include Gaussian Mersenne Norms and conorms and SophieGermain primes when p=k*2^n1 (but excluding p=k*2^n+1) where p is the smaller prime of the Sophie Germain pair.
I'd like to suggest that we resist the temptation of adding high weight Proth primes, k*2^n+1, because one has to stop somewhere Of course everybody is free to pursue other sideprojects unrelated to RPS. Specifically, for high weight Proth primes there is a project started by Robert and Phil Carmody where I took part for a while but currently it has no primes in the Top5000 As for 4*3^n1 note that prof. Iskra (whom I think you already "met") developed his own method but I think it works only for 4*3^n+1 and he already reported tens of primes of that form.

I just created a new thread to discuss new subprojects.
If you agree I'd like to suggest that you lead the GM/GQ efforts. Can you tell us for the beginning the status of the search, and what software is required to search for such primes/PRPs. I beleive LLR alone is enough but it has to be one of the latest versions. Is that right? Info on some illustrative exe times will be appreciated as well.

k=2 and k=4 @ base=3 tested till n=1.13M
112*113^n1 tested till n=240k (looking for the first Williams prime for this base)

I release 112*113^{n}1 @ n=290k.
