Not sure either, but I"m guessing that, rather than running any more Satellites to this (somewhat pointless if you"re already one of the ones who paid their £100 last night), the remaining seats will now only be sold via the BuyIn link which has been left on the home page.
Running more Sats now will no doubt attract some of those who have already paid for their seat, making it an Admin nightmare in terms of whose transactions would then get processed. It would mean tying up all BlueSq names to payment transactions etc.
