Here's another example that seems fairly easy. Yet it's writing to the app.config.

>>Warning: As a rule of thumb, it is not good to write back to the config file. The framework does not include this ability for a reason. If you want your application's users to not require administrative rights then it is always a better idea to store settings in the user's documents & settings directory or in the registry if needed. That said, this won't break anything and does come in handy for utility applications etc.

>>1. Why not? Isn't the point of App.config to save app settings?
>>2. If not, then where's the best place to save user settings?
