Massive amount of info to read, sorry if I appear lazy but I'm exhausted.

I was "interested" in the first page, post #19: https://bitcointalk.org/index.php?topic=422129.msg4592552#msg4592552

How do I get 4 million of NEM?

You may either wait for the coin to launch and claim your stake then via bitcointalk-account or you may claim your stake as "pre-tradable" token in nxt-ecosystem. This token you will be able to trade for real nem too after nem is launched.

edit: one stake is a million nem, not four million.
