We are supplying a lot of useful materials free for you to use in your activities. We would like to keep our servers running and pay our developers and writers something for their time.
If you appreciate our resources, you can become a lifetime member for a one off fee. It's mostly a trust and appreciation payment but you will also be able to access some extra files and resources as a thank you. We have put in a lot of time and effort over the years and hope that you feel that it is worth something.
