We cannot have the first Imperial Althing to make any of these changes without first having Imperial Officers, we cannot have Imperial Officers without an Imperial Election, we cannot have an Imperial Election without a Coronation Event and said event will need to be hosted by some group of people. That group of people will need to be selected even if it turns out to be the NEBoD that will need to be discussed and confirmed.
I disagree. I think that we are fully able to have an Imperial Althing without having Imperial Officers. We will just have to use individual group votes to execute it and permit us (the BoD) to administrate the Althing. I don't forsee a large problem with it, as we will not be requesting a tie-breaking vote or any such thing - just the "power" to set the agenda (in full view, to ensure that we're not holding anything back) and set down dates, as per the Corpora. We will also collect the votes and tabulate the data, though I wouldn't be averse to doing all of this openly either.
All of that said, I will be posting on each group's board asking that they vote within their groups' April Althing to permit the NEBoD to hold the first Imperial Althing, shortly after our requested affirmation time of Great Eastern.
