^^ Not trying to pick a fight here, but it's damn hard to find a lot of this info. I have seen this explanation many times here myself, but there is a LOT of info to sift through. Even if you search, you get dozens of results you have to read through.

If you're sick of "having" to explain it, don't. No one made you. THere are a LOT of people on here who can't wait to help out those that are just starting out, and see it as a priveledge, not a burden, to help others with queries or problems.

NO offence intended.

Rant over.
