The big shiny button below leads you to a PayPal site. Try the button, if you feel inclined — you can back out whenever you want.
Some more fine print: I really wouldn't like to see your generous gift go to some hacker who has shed not one drop of the four years of sweat that Beren cost me. Unfortunately, web pages are easy to clone. I've done my poor best as an amateur website designer to make that difficult. One such ruse creates the watermark image in the banner below. I have set things up so that you should see a similar, but not identical image in similar, but not identical colours, every time you reload the page. Of course a hacker could just keep a single image and delete this text, but at least, if you see it, you can be fairly assured that this is MY page and not someone else's.
Damn, this does not seem to work in Safari.
