I'm trying to learn the Korean Language by using the internet.
I found that Koreans have three different Roman systems. Now sometimes people even come up with their own system which further complicates communciation.

For example, the Korean phrase 안녕하세요
If this is the official way of writing it, then it should be
an-nyeong-ha-se-yo (NAKL system)

NAKL system makes it difficult to understand how the word should be pronounced, but only how it's the official way Korean spell it.

Likewise, the word Seoul is the proper NAKL system of spelling which would translate to 서울
Now we do not pronounce Se-oul but like Soul.
Soul is the M-R system in Korean. MR system is not an official system.

From what I have researched, M-R has been around for 20 years. This makes it more popular than the new NAKL system, which was created by the official government on 2000.
NAKL will become more widespread, since the Korean government has started changing all the writings from M-R to NAKL.

M-R is widely used for non-Koreans, because it's easier to learn how to pronounce.

I've decided to learn Korean using the newer system, the NAKL system.
Learning to pronounce will be a harder obstacle for me which I am prepared for.

Since I do not learn from an official textbook, I do not know the proper way of writing Korean. My accuracy is based off the precision of the websites. So far it's been okay, but I found a few different ways how people write "My name is... "

Books that are old will probably use the M-R system for the Romanization. However, the Korean (Hangul) word should not change. How is it that people still write it differently??

What is the proper way of writing "My name is ____ " ?

저는 _____ 입니다
or is there another way of writing it?

I didnt even know there was Different system (NAKL or M-R) to learn Korean.

Anyway when you are introducing yourself keep in mind that the person is
a.Older than you.
b.Same Age as you.
c.younger than you.

a.저의 이름 은 ___JOE___입니다.
eg. My name is JOE
or 나의 이름 은_______ 입니다


b&c.나 는 _______ 입니다. eg. 나 는 JOE 입니다
I am _______ . I am JOE.

I hope this helps. :)

cheers
Joe

"PVA GLUE" is right. He is a native Korean, by the way!
I am not; only an American student of the language for a few years.
Unfortunately, the Korean Government tried more than once to translate Korean into English. They did an abominable job. Never approaching the old
M-R system. Suwon cannot be spelled "Suweon" and pronounced properly by any stretch of any native English speaker's imagination. "Jeonra Bug Do" in no way approximates the actual pronunciation of the actual 전 라 북 도. When a person sees a word in English, his/her life experiences dictate what pronunciation emerges.
Ignore all references to any system that purports to help you "Romanize" Korean. Korean does not translate readily into English, as a Germanic or Arabic language does. You may already know the sounds and spellings of Korean.
Use your KOREAN DICTIONARY to spell, and your TAPES or NATIVE TEACHERS to pronounce. Learn to read KOREAN. If it takes you more than a week, you didn't pay attention. Learning the MEANINGS of words takes time, but learning to JUST READ, is unbelievably simple! R, L, F, H,V, W and variations of J,K,G, CH & SH are pronunciation problems that have to be overcome. Listen to the tapes.
Do not spend ANY more money on ANY book that has English next to Romanized Korean that purports to help you pronounce! Useless!

I am a failed student of the language, but I would agree with Mr. Joe. Don't worry about romanization, and don't try to go from romanization back to Korean spelling. The language is hard enough as it is to waste time on a blind alley like that. And even in the MR system, the romanization did not lead to zero problems with pronunciation - like with Busan/Pusan. Busan is probably closer to the usual pronunciation, but it isn't totally clean. There are sounds in Korean that simply do not match any letter or couple of letters we have in English.

Also, like PVA_Glue pointed out, word usage and grammar changes based on the relationship between the speaker and person spoken too - usually based on age difference. This even effects some nouns you might use - you use one noun for the same thing with people closer to your level or younger than you, but you use a different word for the same thing if talking about or two an elder.

And lastly, on MR, one of the first panels the Korean government set up to look into romanizing Korean came back and actually told it that MR was a good system and that it was not worth trying to come up with a better one, but the Korean government said "no" and told them to create a new one.

Part of the reason was the fact MR was made by non-Koreans, but part of the fact was the difficulty in both printing and understanding what the special marks meant in that system - the horseshoe shape over some of the vowels.
