Although text messages are usually sent without any spaces at all, when writing Korean or for a longer letter, spaces are rather important.
Fortunately, a friend told me abou this new site that seems pretty cool — 자동 뛰어쓰기.
Sometimes where to put spaces between words is difficult to figure out in Korean. However, here if ou can put your Korean text and it will put in automatically correct any spacing mistakes.
I’m going to try to use it for my lang-8 diary entries before I publish them to double-check to see if my spaces are correct.
