You know, even though I don't think that trading is technically limited to one MM for the first 30 days, I do believe it may be the case from a practical standpoint. I mean, why should additional MM's bother to do the DD required when filing a Form 211 when they can just wait 30 days and then piggyback on the original MM's filing?
Without news or more MM's trading this I don't see much happening here in the near future.
