I hope that I didn't come across as beating on you because that wasn't
the intention...the fact that you are posting on a group such as rafm
shows that you are indeed all about learning....

I would suggest you go and do some reading on the following sites:-

http://faq.thekrib.com
http://www.netmax.tk
http://www.skepticalaquarist.com

and Carl's website blogs....which I can't find a link for general access
to at the moment but I'm pretty sure he will provide it....

All of these will give you a good starting base....but you WILL have
follow up questions so feel free to ask....
