If you have enjoyed this web site you might like to make a small financial donation by Paypal to firstname.lastname@example.org, but please don't feel obliged to do so—my overheads are of course quite small and I do not regard the few hours each week, spent on upkeep of the site and responding to emails, as a burden.
For GB£5 donated this way I'm willing to send you a solution to a problem of your choice in the archive.
I pledge to pass on 50% of all donations to cancer research.
