Unfortunately the IPO ended about a month ago. There is currently a public auditing of the Stakeholder List to weed out large multi-accounters. People on the waiting list will be used to bring the overall stakeholder number up to ~3000 people after this process is over.
I saw the list and there is a group which is accounts which has just posted once for the stake and has not been used. Those stakes can be recycled for newer members.
This coin has a great potential, and as a stakeholder, I am following the developments very closely and will soon start helping out the best I can. Please drop the idea of cancelling stakeholders who have posted only once.
I was one of those people who only posted once. I know someone who acquired a NEM stake (initially had no clue she had some) and as far as I know she only has the one NEM stake and is more inactive than me.
Inactive being a weird word - both of us lurk and keep well informed about the coin, we just don't login or post much (there's really no point of either).
In my group of friends and acquittance of work, I know several people who missed the registration period but intend to purchase NEM at launch (these same people wanted nothing to do with NxT or Mastercoin). There's definitely a lot of enthusiasm about NEM - one of the few IPOs out there that was fair, well distributed (3000 being better than 30 or 3 people as per most coins) and it wasn't a big ponzi scheme (I'm reminded of how Mastercoin was ecstatic about the huge amounts it raised but failed to realize that made it look shady to subsequent investors).
