Interesting updates from a few of the other "NXT clones":
PiNX:
For details left unexplained, PiNX cant lead this project.
In the end, all I have given you is a vision. It is up to community to make that vision a reality.
Goodbye.
NEX:
Please do not post here about 'being interested'.
You need to go to
http://www.nexcoin.net to submit your interest.
My mistake! I have already given my email, I just saw everyone else doing it so I assumed you had to to claim your stake.
By the way, how many coins will NEX have? And is there an ETA for release?

100 million on release, 1 billion total.
3 weeks.
Are there any other notable ones?
I am suspicious of FrictionlessCoin's intention. Looks like he is trying to make a POW clone with certain percentage of premine but he still claimed making POS coin, There is no workable pure POS code bases available for him to clone so what he is trying to do ? maybe he tries to re-write on his own because he does seem to have a lot of free time.
