Fair enough. Maybe give advice on how to find them....but why give the answers on a plate.....correct or not?

I will help anyone if I can, I actually wrote a big post yesterday ready to send it through on his PM like I have been doing with another member but unfortuantly he's either turned off his private messages or is account dont allow them. Didnt want to keep a thread dragging like we've seen before.
