I've posted a new build for Subscription Tools in the downloads section (members only).

New Functionality Includes:-

• You can now configure currencies per plan (or leave them as the default setting for the module).
• Receipts will now store the currency code of the transaction allowing you to change currency within the module and not affect old receipts.

Fixed Bugs Include:-

• Fixed a minor token issue with [FEE] (for the email invoice) and currency selection.
• Incremented version number on assembly to handle DNN 5 installations better.

Thanks again for all your feedback!
