Welcome.  If you look to the left of the blog title you'll see a tab that you can use to access all the pages I've created.  These will be filled with information eventually.  The information about this blog's copyright is found on one of the pages.  I use a Creative Commons copyright which allows you to use and change the material under  minimal conditions (essentially recognition, non-commercial use, and likewise copyright on resulting works); more information can be found on the copyright page.
