Jezz, @EnergyNumbers. Your level of sarcasm is incredible. I'm not a novice either and I participate in several other sites here. Feel free to ask the admins to close it so only you can participate! Part of building a community is being responsible, being serious and allowing everyone to participate. I don't consider and will never consider myself an expert in any topic. There will always be someone that knows more than you so don't consider yourself an expert, and there will always be someone that knows less than you, so don't shut them up.
