Difficult one to make a call on really. Some people will respect the system, and others could make life a living hell, calling at all sorts of silly hours with stupid questions like 'my hot water isnt working, is this normal?' kind of things.

It would either have to be limited to something like 3 questions and no more after that or for reward. Then it would be up to the individual helper whether they wanted to assist any further.

The last thing we want is someones dream turned to a nightmare through trying to be helpful to others!
