Important Update:
Following the recent changes and improvements to the Open Exchange Rates service, App ID signup is now open - it's free for personal use, and extremely cheap for everybody else.
App IDs will be required for all users from the end of August. More info here.
You can sign up easily at the signup page - any questions, send me an email!
