How to better explain project extensions?

[jbranchaud]

The explanation in the Project Ideas Template of extensions:

Any interesting extensions to the project that the user can attempt after solving the base project (optional)

may not be clear enough. Suggestions on how to make it clearer?

Extensions are basically exercises for the reader or extra credit problems that a person can attempt after completing the base challenge. This is great for situations where a person finds a particular project too easy and wants to make things more challenging.
