I took the liberty of creating one for you. This is what it will look like in a visitor's browser:

I don't seem to have permission to attach the icons to this post. I uploaded them (zipped) to http://www.mediafire.com/?0m12pmzmns4jo20 .
That zip file contains the favicon.ico file which displays in browsers, and a .png file which is used by Apple iPod/Touch/Pad.
It's simple to install:
1. Put those two images in the server root (the directory where http://www.psychforums.com/ maps to. Sometimes called the "base directory" for the website. Often /public_html)
2. Add the following elements inside the HEAD element (usually styles/prosilver/template/overall_header.html )
- Code: Select all
<link rel="shortcut icon" href="/favicon.ico" type="image/ico">
<link rel="apple-touch-icon" href="/apple-touch-icon.png" type="image/png">
Hope that helps!
