I am working for an international NGO with memberships. They want to be able to sell memberships in USD, EUR and GBP. The contribution forms will deal with this for donations, etc. The contributions form will also switch the membership currency to the one give in the Amounts page, but the value is the value given in the Membership type. Logical enough, but the membership type seems to be tied only to the default currency. Is there a way to define a membership prices set or even a separate membership in another currency?
