Here's the thing, I've already gone through this tutorial. The problem I'm having is that this tutorial really doesn't go in to much depth. What I want to know is how do I tell Joomla that a particular article should be placed in my content DIV tag within my template? Can somebody point me in the right direction for this? Maybe an extension or plug-in for Dreamweaver 8 that would help me accomplish this?
