We have donors from all over the world and it gets very confusing when we receive a donation in dollars that then shows up in GBP on eTapestry.
Our team is very small and it wastes a lot of time checking where the donation has come from and then working out the exchange rate on the day the donation was made.
Either eTapestry could reflect that the donation has been made in a different currency, or else automatically convert it into the equivalent GBP amount.
