You're here because you want to contribute. It's not a tax deductible donation, but if you like these web apps and want to see them stay free and void of ads, your donation will help offset the costs of running them.
It is my hope to keep these web apps subscription free and advertisement free, although it is getting difficult as they become more popular. There is the cost of hosting and the I rely on several services that cost money for the weather forecast data and the mapping which are based on how often they are accessed.
Click the "Donate" button, it will take you to PayPal.com where you can type any dollar amount you feel like giving, and you'll be able to pay with your PayPal account or credit card.
Thanks for you support.
