I use, along with a LOT of the EU WoW community as a shortened Yes, however it has another meaning in local dialect.
But you seem to just want to argue for the sake of it. Im not going to entertain you. YOU can keep Kelzio company on my ignore list.
I've been trying for the best part of 5 years, I used to have a mentor at university who helped me work around it but it didn't really help. The only thing that helps is if I take my time but there isn't all the time in the world to waste on worrying about whether I used the correct homophone, or got the letters the right way around. It's not like I really need to care anyway, since I work with my hands instead of in an office.
