Joomla has a rich set of extensions to provide just about any capability that you need for a robust e-commerce, social media, or organizational web site, but there are sometimes situations where it would be nice to do something just a little differently. For this, you can write your own extension. Bruce Moore will go through the steps for writing your own plugin or module, the two easiest types of extensions to write.
You do not need to be a programmer to benefit from this meeting; understanding the basics of extension development will help you in diagnosing problems even if you don't write code.
