notes:

• number of entrees may vary, or become adjustable if needed
• proposed monthly budget menu choices: 5.00, 10.00, 15.00, 20.00 USD
• an additional link or button will be added for viewing the recent payments/contributions screen

$5/month minimum for 1.0 is best, based on user feedback in our home region. We'll figure out other minima for different locales for 1.1, 1.2, etc.
