I imagine that Nefario will only be sending out lists once. That means everyone needs to provide GLBSE with their information before the list can be sent. There are probably people who had accounts and forgot their login or other strange issues that will need to be worked out first. Just be patient. Things are very much in motion and exciting developments are on the way that will greatly please fans of this operation.
I would hope that he's waiting for a critical mass of users to fill out the form, but certainly not every
user. I'm sure a few people simply forgot about their accounts, forgot their password, or aren't submitting their information for other reasons. Nefario should send out the info to asset issuers when the amount of people submitting info has slowed to a trickle, and simply include the number of shares that are owned by people who have not submitted information. This way asset issuers can set aside dividends for when the holders of those assets do
submit their info.
Exciting developments sound exciting.
