Donations keep us up and running.
Running this site does cost money, the more successful this site becomes the more cash my ISP demands to keep it going as their bandwidths are affected.Unless you wish to order the tutorials in special formats the tutorials are free of charge. If you are a teacher or lecturer and intend using my resources in the classroom then you can help keep this site up and running by donating cash, or ordering tutorials in PDF or DAISY format. Please note that although the tutorials are publicly accessible, I retain copyright and my written permission is required if you wish to use any of my work for a commercial purpose.
