put a sell order for namecoins on BitcoinParking, but I don't see it on the sell list
just trying to get my namecoins converted to BTC
Does your balance still show your namecoins? If so, your order didn't take into account the fees. Click the "Calculate" button and it'll tell you how much to take into account for that. If your balance has the order subtracted from it but it doesn't show in your list of orders then the trade went through immediately.
