Mrrzy - I'm surprised you can even bear to read some of the stuff that's being spouted here. It must be painful, and you have my admiration for even bothering to contribute. I hope my own rantings have not offended you in any way.

Steve - thanks for the Darwin information, I'm ashamed to say I haven't actually read it either, only read about it. Maybe now I will..

Pete, Ron - I now realise I was wrong to dignify your posts with a response. Please, please take your poison elsewhere, preferably dark and quiet.
