A couple of points:
This would not have been a grammatical error, but a spelling error. There is a distinct difference.
If your reading ability is as up to snuff as you claim your writing ability is, you will clearly see the first “childish insult” was your own post. If you can't take it, don't dish it out!
If so terribly busy studying and working, no need to take time out of your intense schedule to patrol for either grammatical or spelling errors, otherwise you've lost that argument.
Finally if so concerned about the integrity of this as a board about accounting why deviate from that yourself? Your message had no relevance to accounting whatsoever.
