This is trolling but you are welcome. Yes this is the most use I have received from being a TA in college.
Really - There was nothing incorrect about the way I used it.
Usage - Since I was referring to grammar, it's actually correct.
You - Yes, typically addressing the reader as such is frowned upon, but in this case I was attempting to construct a condescending post. "You" has an uncanny knack of coming off as condescending when instructing others, IMO.
May or may not - You would be correct on this, but it's not necessarily wrong.
The fact that - Wordiness is just being picky, there's nothing wrong with it.
Your - Read back to "you".
I - Read back to "you".
An Ultima Online forum - An is correct here since the 'U' in Ultima is making a vowel sound.
Contractions - Moot point (like many of the things you have pointed out), this is not an academic writing assignment.
Commas - You might have me on some of those.
Uhh, if there was anything else I missed, oops. The point is, there's barely anything wrong with what I wrote and your troll attempt has been foiled. Muahahahahaha!
