The purpose of this tutorial is to explain "debug demo" etiquette and how to make it easier for others to get your project and look at what's wrong.
What is a Debug DemoEdit
A debug demo is basically a demo project that you create for the purposes of debugging.
Creating a Debug DemoEdit
Here are some things that would make things easier for everyone.
If you want someone to look at a script compatibility issue, chances are, you do not need to include 200 MB worth of graphics and sounds in the demo.
You should ideally create a new project and only include the minimum that's necessary to reproduce the problem. This allows others that are trying to help you to download your file faster and to pin-point where the problem is faster when there aren't a lot of other scripts that may not have anything to do with the problem you're having.
