Let me (hopefully) make it clear what I mean when I ask you to create a link to my page:
For example, if you have a multi-page site, and you use my backgrounds on some of your pages, then you could put a line something like this on your home page:
Some of the backgrounds you see on these pages were created by <A HREF="http://www.abstractfactory.org/forrest/gallery/">Forrest Cahoon</A>.
A one-liner at the bottom of your page will not detract from your content, and would make me very happy. The exact wording I have above is not important -- it's the thought that counts. (The liberal use of words like cool, awesome, etc. is something I certainly wouldn't frown on :-))
If you have any questions about this, please ask forrest at abstractfactory dot org.
