Do you mean the post currently at the top of your Oekaki BBS?

It says:

いつぞやはメールをありがとうございました。
お礼にアーサーを描かせていただきました。
…って、日本語じゃわからないですかね(^_^;
英語話せないのでごめんなさい。
とりあえず何のキャラだけはわかってもらえると良いのですが。

Which says:

"Thank you very much for that e-mail!
As thanks, I drew this picture of Arthur-- but, uh, I guess you can't understand what I'm writing if it's in Japanese. I'm so sorry that I can't speak English. I do hope you can at least understand which character I'm drawing!"

While I can't say anything until I see whatever you originally wrote using the translator, my understanding is that Minato understood and appreciated your attempts at communication.
