do what i did for the first few days i registered here, i just went through all the different posts and READ.

do not expect to learn everything from a few sentances answering your 3 questions. we could sit here for years answering your q's and still wouldnt be done

i could answer all your qs in one word

1) all of them
2) NO
3) yes

see, didnit learn anything. read read read my friend.
