What does everyone think of this idea . . .

Never Give Free Advice
The idea being that it'll never come back at you if things go badly . . .

Seem's to me that this is the opposite of this forum . . .

Discuss, giving the reason behind your decision and what factors influenced you.

Your friendly neighbour asks for some help/advice with an IT matter. Do you

(a) say no - on the grounds that should it go wrong your not insured for liability
(b) say yes - but ask for a written contract to cover the insurance
(c) say yes - and offer some kindly neighbour like help

As they say . . . It's over to you . . .
