so I see in 6 hours NEM is released, I'm no stake holder so I would like to buy NEMstake. Do I need to send them somewhere else before the 6 hours window or comment here or how would I convert the NEMstake to NEM later?
thanks!
You will be able to convert your NEMStake to actuall nem after the release which is still months away. 
The exact process isn't worked out yet.
