[Ryuondo]

俺はリュオンドだ。二十三歳だ。日本語を五年に勉強したぞ。
おれはリュオンドだ。にじゅうさんさいだ。にほんごをごねんにべんきょうしたぞ。
Ore wa Ryuondo da. Nijuusan sai da. Nihon go wo gonen ni benkyou shita zo.

A form for all learners.

Just call me Ryuondo, I am a guy with a female avatar, so the use of "ore" isn't odd. I've been studying Japanese my entire time in college, so for about 5 years now. In order to aid myself with J.E.T., the Japanese Exchange and Teaching Program, I'm going to be tutoring our Japanese program's 後輩(Kouhai) this semester.

Word of warning, I tend to use gender specific vocabulary.

Minna san, hajimemashite! Nihongo ni tetsudau koto ni kimemashita. Douzo yoroshiku.
How do you do? I have decided to help you all with Japanese. Pleased to meet you all.

As I don't know how to do furigana on firefox, this will have to do. Don't let age of beginning put you off. As we all know, even native speakers of any language still learn all throughout their lives. We just have to work hard to catch up in the one(s) we're learning.
