Template overrides are now being very widely used in some of the better produced templates, but do you really understand how they work?  Have you got a clue what the MVC concept is all about?  We had to do a bit of research ourselves to be able to explain it to others in "non geek speak" - hopefully you'll find this presentation useful. 

Please note that there was a lot of discussion relating to this presentation - why not come along to our Joomla! User Group meeting to find out what you're missing!
