The Llc's I know about, and there aren't many, have member counts in the single digits....4-6 is probably average....larger than that and they tend to incorporate. The count would be on the Form D if one gets filed....I still think that MAY happen. It honestly shouldn't matter much to you (of course YOU get to decide that) because there's no dilution involved based on the share retirement and no matter how many "new" NNAB investors there are your share of the pie wouldn't change anyway.
BTW, I think they meant to say "accredited" versus "non-accredited". This is part of the definition of an accredited investor: "had such knowledge and experience in financial and business matters so that each was capable of evaluating the risks of the investment".
