I saw a message on Skype. Happy Birthday! Bon anniversaire!祝你生日快乐！
Herzlichen Glückwunsch auch von mir!
So glad to be a part of LingQ. Have A Very Happy Birthday, Steve!
¡Feliz cumpleaños Steve!
Happy Birthday, Steve! If I hadn’t come across you and the LingQ system, my life would not have been so satisfactory as it is. I cannot thank you enough!
By the way when you have the chance to come to Japan next time, please visit the western part of Japan too. There are so many LingQ members here in KANSAI. Let’s talk about language learning as we eat TAKOYAKI,(or whatever!).
I look forward to doing that Hiroko. Grazie and thanks again to all for the kind wishes.
Happy, happy, happy! 
С днём рождения!
Стив, по русской традиции хочу пожелать, чтобы у тебя всё было, и тебе за это ничего не было!
HAPPY BIRTHDAY!!! BEST WISHES!!
Happy Birthday Steve!
スティーブさん、お誕生日おめでとうございます！
I often listen to the classic episodes of EnglishLingQ podcast with my MP3 player. I like them. You always encourage us and entertain us. Thank you!
Have a nice day!
С Деём Рождения, Стив!
Желаю тебе всего самого лучшего, и спасибо за то, что ты делаешь.
Happy birthday Steve Kaufmann!
Steveさん、お誕生日おめでとうございます。
I’ve just finished reading your book “The way of the Linguist” in the format of a book recently. Your messages always encourage and stimulate my attitude towards English learning. I was also deeply moved by your commitment and enthusiasm to the creation of the language learning system written in the section “Postscript: The long road”.
Ich wünsche Dir alles Gute zum Geburtstag!!!
Thanks again to all the well wishers and I had a great day. I drove in the rain and wind to get to a meeting of teachers in a small sea side town in Portugal, and did not get back to the hotel until 10 in the evening. And then my wife and I had a great birthday dinner.
