Rule 1236B (Geoff: Mutable) Currency Regulation.
Amend 1236B
A currency holder may offer any amount of currency to another person, providing they do not offer (in total) more currency than they hold; they shall be known as the "Offerer" throughout this rule. The person to whom the currency is being offered shall be known as the "Receiver".
The Receiver may accept the offer at any time until Offerer retracts her/his offer or until the end of a game. All outstanding offers are retracted at the end of a game.
Upon accepting an offer the Receiver receives the number of units of currency, N, offered providing the Offerer has at least that amount of currency. If the Offerer does not have this amount of currency then the offer is automatically retracted. Once an offer has been accepted it may not be retracted or rescinded (providing it was within the law at the time of the acceptance).
The Offerer shall have subtracted from their amount of currency the number of units of currency, N, in question; the Receiver shall have added to their amount of currency the number of units of currency, N.
