Silly question, but I must ask.
Is anyone from the Neucoin project, past or present, working in, or anyway involved in decred, past or present?
I'm not familiar with Neucoin at all so in my case that is a definite 'no' (and I'm pretty sure that is the case for everyone).
Anyway, you can see on github exactly who has been involved so far (not counting people who have only been involved in btcsuite) by going to the people link
