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

New Functionality Includes:-

• Added "Module Currency" selection to "View Options", this should allow you to use it on sites that are non US dollar based. The list of currencies is maintained in Host -> Lists.
• Reminder text should now be saved when sending reminders (pre-loaded when visiting back to this screen).

Fixed Bugs Include:-

• Fixed some number formatting issues.
• Removed some logging alerts used for debugging.
• Fixed a date bug when using it for multiple subscriptions on the same site.

Thanks again for all your feedback!
