@devast8a I had thought of that, however I assumed the community would be able to figure it out. But you are certainy right... I should probably try not to create a paradox.
Of course it is up to petrol as to what advice he listens (reads?) to.
I'm just suggesting that advice is not taken from people unknown to petrol, as petrol has no way of validating the advice provided. That is not to say that the advice provided by the community is wrong though...
