I like the idea and would donate as well.
The idea to be able to donate online has been addressed at another independent snowmobiling site I have frequented for years. That site is kept operating, and free, with the help of a specially dedicated PayPal Donation account. Donation button seems to be added to the site only when he needs a few bucks for operating expenses. Simple enough, click on the button, enter the amount of your donation and your PayPal info. All taken care of securely through your PayPal account. Of course if you don't have an account it lets you set one up.
NOTE: The site I'm referenceing is kept running on a shoestring by a great guy named Ray Booth. I hope John doesn't mind that I have listed a link at the end of my post. (I originally found JohnDee.com through a link on Ray's site.) He doesn't currently have the donation button on the site, but he may be able to answer any questions on how it was done.
Thanks for the great site John!
