Okay, correct what I did wrong if you think you're so great at grammar. Then I can tear you apart and tell you word-for-word on why you're wrong. :) I proofread University papers as a job, so you're going to have a hard time convincing me that I am wrong. Do you know what prepositional phrases are? Do you know what commas [i]actually[/i] do and when they are needed? Do you know when to use a comma after a prepositional or introductory phrase? Please read the Gregg Reference Manual when correcting my grammar as well to make sure that everything is correct. I'm sure you have one of those, right? Do you even know what it is? You probably don't without googling it.
