Feel free to correct mistakes in my comments and articles. Also, can you recommend a guide to English punctuation?
Would that be British or American English punctuation? ;)
http://www.englishclub.com/writing/punctuation.htm is designed for people learning English as a second language. Note: their section on the comma , would be corrected by some, including me, to I speak English, French, and Thai. The comma after French is called the Oxford comma. Its use is debated.
The Wikipedia article has a section comparing European (you perhaps?) to American and British practices. http://en.wikipedia.org/wiki/Punctuation#Conventional_styles_of_English_punctuation
