When posting CPs for sale - can there be a confirmation window showing the total amount you will receive from the sale? If some makes an error in posting - like listing 100 cps for 7k instead of 70K each or a transposition error - 17K instead of 71K - folks would get a confirmation window that would say - "Are you sure that you wish to sell these cps for XXX chips? Please confirm or revise your listing"

A window like this would allow the seller to be able to correct the transaction before it gets listed.
