Use of text and images
You are welcome to use material from this site for educational projects, presentations, and the like, without asking me. How you cite or credit it is up to you. If you want to post some of the content on-line, I ask that you at least include a back-link to the page or pages it came from and some appropriate credit. If an image is credited to another party you will need to contact that party, not me, before you can reproduce it. I also ask that you don't just copy and paste whole swathes of my work!
Thank you for respecting.
