Use of period and quotation marks

I'm sorry to disagree, Tony, but your answer is incorrect! It can't be assumed that everyone who reads this page is an AmE user. I'm a BrE user. Rules are varied and like Lewis said, there's a write-up in Writing tips & tricks.

Basically, for me, the punctuation is within the quotes if it belongs to the quote, otherwise it's outside. But I think the AmE users prefer them inside.

The period should be used inside of quotation marks.
