Does anyone know of a module that would supply a FAQ type system where an employee could go to find answers to commonly asked questions from customers? i.e. Customer calls in and asks:

What days do you deliver to my area? or How tall does your crane reach?

The employee could then search this database of answers, give the customer the best answer then it might ask the employee of this solved the customer issue and track that or offer other suggestions if that did not solve the issue.

Thanks!
