you are absolutely right @yofie ..when a domain on Namejet is on pre-release means you have a chance to bid whatever amount you wish to backorder the domain name and give you a pass into a private auction that will be held after the pre-release date elapses and will last mostly for 2 or 3 days featuring only members that placed a minimum bid of $69 bid when the domain was on pre-release..After the private auction ends, any bids after that will be a "WISH LIST" auction.
This is what i noticed and if i am not 100% correct then feel free to add whatever i missed
