I just put together a small tutorial on organizing and managing event sheets (my method of course) for the people who are new to Construct. It really is nothing much, not even worth looking at for most people... but you know... I just had to make it, because I was introducing Construct to some friends who I am working with and I just wanted to show them how I organize my Construct projects. It can be found here: http://darkchaosstudios.com/tutorials/organizing_&_managing_tutorial.htm
Note that it is based off of a more OOP type of feel. It is what I have learned works best when actually programming, and I found it can be applied to Construct as well.
