How much, or how often you contribute is entirely up to you. It might be after every contest, or when you download a new version, or once a year. Every single contribution, regardless of how trival it may seem, is appreciated because I work from home - and I pay my taxes on everything you give.

If you can't afford to contribute, that's OK - you'll still get the same support as everyone else. Either way, please mention you enjoyed using SD when sending in your Cabrillo logs, so that others will be encouraged to try it.

Your credit-card donations are processed by PayPal and are secure. Any credit card is fine - you do not need to have a PayPal account to use your card.

Here are options for single payments in Sterling, US Dollars or Euros.
