[citation][nom]oxxfatelostxxo[/nom]Guess ill have some fun with it then, heh.. 1 maybe..Now i could be wrong... English comp was quite a few years ago for me, however im pretty sure you technically arn't supposed to use a comma before "but"..=/... sigh i hate grammar police.[/citation]
Wasn't going to say anything as the guy's post was mostly error-free. Since you guys insist at poking at it:
1) "Amount" is wrong as it is used with uncountable items, which "articles" is not. The proper term is "number."
2) "Error free" should be hyphenated like I have above.
You can use a comma before words like but/and if they join independent clauses (clauses that can stand alone as a sentence) OR if the sentence could be misread without one due to how it's phrased.
Anyway, I'm not here to nitpick on grammar--only posted since that guy was curious.
