This website is totally free to use, and has no external source of funding. To make that work financially, the site is advertising supported. I've tried to keep the advertising reasonably unobtrusive, with just Google Adsense in the primary sections of the pages and sponsored links underneath the comments. However, this does limit the potential income somewhat and means that development of the site is on something of a shoestring.
If you would like to suport the site more directly, you can do so by making a donation using the buttons below. This is completely optional, and the site will always be completely free to use irrespective of income. But it does make things a little easier when it comes to funding further development.
