My actual user page is http://en.wikipedia.org/wiki/User:G_Purevdorj.

My Japanese reading level is intermediate: don't assume that I can understand any nuances, but for a scientific essay on a familiar topic one day's work will do. My active command of Japanese is worse.

When reading simple Korean sentences with the help of a dictionary, I have a fighting chance, but I don't know more than 100 words of memorized vocabulary and only some little grammar, so it is probably no good idea to chance it.
