I've started making more tutorials and putting them up on here. I was using a crude method of divs and classes to highlight different code which looked ok but I'd seen it looks much better on other sites so I went looking and found Syntax Highlighter which does an amazing job. I've used it on My Twitter integration tutorial locally and a quick hosted demo. I think it makes the page look a lot better. I'm gonna add it to my 599CD Classroom, hopefully in the next couple of days.
