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.
