The holding tank is a locked tourney. Once you qualify through a satellite, then you cannot unregister.
Once the remaining seats are sold on Thursday, we will have a complete player list for the event.
Should anyone have to give up their seat due to unforeseen circumstances, then the Seat Exchange Board will be available on the forum as it was for the previous season.
I"m not sure whether Betfair Poker will allow you to qualify for the same holding tank more than once, but these satellites are for qualifiying for an APAT live event, so once you have got your seat, there is no reason to try and satellite in again. All you are doing is taking away the opportunity for another member to qualify.
