As another HNer kindly pointed out to me, the rule requiring the filing of a Form D 15 days before any general solicitation is, at this point, still just a proposal. But based on what we're seeing here, it does appear that at least some of the companies already engaging in general solicitation don't even know that they'll need to file a Form D if they're successful in raising funds.
