Dear Sir/Madame web administrator,
The front page is annoying. I want to change it.
Also, stop saying "..., Mun" "..., Mun" - there's a way to address people properly, and cutting off people's names into bits isn't one of them. If you really must address me directly, "Mr. Choi" is fine; we're not on first name terms, and it's not professional of you. If you really want to dispense with formalities, then at least have the courtesy to use my full name. Whichever way you go, no more of this "Hi, Mun" ****, please.
Thank you and have a good day.
