Okay, you may be wondering what is up with the iFrames. Totally, annoying I know. However, blogspot has a tendency to replace the < ? ? > all of the time. This site is not straight HTML it's XHTML. Which is cool but it has it's own issues. I'm only doing the iFrames so you can cut and copy and paste.
Like other disclaimers, nothing here is guaranteed to work it's an overview or tutorial. If you feel like something is wacked out, send me a shout, I will fix it and give you mad props.
Please excuse the iFrame for the tutorial. See below.
