Best approach to create a troubleshouting section? I am looking to create some kind of troubleshooting section on a website. Sort of like the Windows help with some sections, questions and answers.

I was thinking of doing this with a regular Book, and write a small form module which allows me to track the page with a "Was this information helpful or not?" question.

But are there possible alternatives, either existing modules or an approach which works best?
If you go down the book route then you can always use the flag module for the "Was this information helpful".

There is also the FAQ module which doesn't quite fit your use case but might be worth checking out just in case.
