Kms hmm

So, i started playing mw2, and then tried to play maple, and got bored, so i realized why mw2 had been so fun, it had been new things. Now im not saying i crave new things constantly, im just saying, maybe a new setting, now now, i cant read Korean, if im gonna learn anything, it will be Japanese. So, heres the thing, almost 90% of the people playing kms i see that point ss on these forums, as well as hs, sw, etc have there name, as well as others and there chat in english. This baffles me, i cant find how to do it, how DOES one do it? I can find ways to get my hands on a kms acc, as well as the client, but i cant understand this. And i would very much like to know.
