Peter,

Very good idea a world of chips database with scan I hope. The traders must be responsible to delete or deduct the chip or the amount that are actually traded to minimize headache and pain to the others who would be interested but the chip is already traded. All posting must be dated and quantitied. Future additional posting must be dated too - like revised listing.

I am looking forward for a follow up posting on the development of this project.
Pete you could also revised or program the 'Trading Post' along this like. Would the posting open to the public? Can non members access and post their trading? Or exlusive only to members? Members will have to register to post with their R before posting for control.
