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.
That is a bad idea in my opinion. There was no statement made whatsoever that you have to post more than once. It would be a needless shitstorm. People will start posting when it's time for them to claim their stakes. At that time, we could have rules in place to distribute abandoned stakes, but would need to be very careful about it.
