The first thing i try to do before posting a question is use the search facility. there is so much information on here as in the end people will just keep asking the same questions over and over again.
 
Just a quick passage for you from the attention newbie thread by Mork

Use the search facility before you post. Incredibly, it's free for you to use. So when asking about the best way to chip your car, whether a whoosy DV will fit - or whatever - ALWAYS without exception go search before you bother asking.
