The person I answered before is on a completely different track then you, just to be clear for anyone browsing this later my previous answer WAS on point to their question.

No, on to the questino for Soyemi. The difference between the installable module and the source code version (which is also installable) are simply the code files or project files (.vbproj, .sln, .vb, etc.). If you need the .dnn file, you can pull that from either the _Install.zip or the _Source.zip before you ever install it. You also can create a package via the Module Definitions area. Each module has its own project structure and what I do in the Forum module may not be done exactly the same in the Events module. My advice to you is to checkout the DNN Professional Modules book that Mitchell wrote. If you are new to programming, there are a few other books I would check out too.
