Webster's New World Dictionary states the comma and the period are always enclosed within the quotation marks. The exclamation and question marks are placed within if they apply to the quotation and placed outside if they apply to the whole sentence. Example: "I'm leaving," he said, "but you may come with me." "Can I go too?" she asked. Didn't I say, "you may come with me"?
Valid punctuation marks in English include the period, the question mark, the comma, and the apostrophe. Other valid marks are the exclamation point, quotation marks, the colon, and semicolon.
Generally, punctuation marks such as periods and question marks will precede the final quotation mark at the end of the sentence.
The punctuation should be adjusted in the quotation. Make sure the quotation marks, commas, periods, and other punctuation are used correctly to integrate the quote fluidly into the surrounding text.
To correctly type a quote, type an open quotation mark, then the exact quotation, then a closed quotation mark. Punctuation that is part of the quote goes in the quotation marks and all other punctuation goes outside of the quotation marks. To indicate you've skipped some words, use an ellipsis, and use brackets to indicate that you've changed words.
In American Language they say like this: "I wonder why she did that." In British English, most punctuation goes outside of quotation marks. Example: She said, "I wonder what they're doing". But in American English, the opposite rule applies -- most punctuation goes inside of quotation marks. Example: She said, "I wonder what they're doing."

The fourteen punctuation marks are used in a sentence to convey meaning, organization, and clarity. They include the period, question mark, exclamation mark, comma, semicolon, colon, dash, hyphen, parentheses, brackets, ellipsis, quotation marks, apostrophe, and slash. Each punctuation mark serves a specific purpose in indicating pauses, separating ideas, indicating emphasis, indicating omission, and showing possession, among other functions.
Quotation marks should be placed around any quotes. In other words, any text that you have copied from elsewhere.
A period goes before the closing quotation mark. The first thing he said was, "I didn't think you would get here so quickly." Source: Harbrace College Handbook, 7th edition, by John C. Hodges and Mary E. Whitten, page 151. The above is true in American English. In Britain, the period goes outside the quotation marks.
You can include the quote - just not the quotation marks. You could post a question similar to...Who said Romeo Romeo where for art thou Romeo - even without the quotes and other punctuation marks, it still makes sense.
