You can download and use these resources for free. I have a few rules, however. It's not much, but I've spend hours and hours making these downloads and I wouldn't like to see them used in ways I don't want them to.
After using the resources, please credit to Horizon Road with the following url:
Don't put these goodies on your website and claim them as your own. Also, don't edit them and say that you've made them.
(I just found out the readme files don't work anymore)
