My first day with ikalki

I am glad to join ikalki and I hope to practice my English here. I think it's wonderful because it's free. I will advise my friends to join too. I look forward to make differently cultured friends around the world. If you find any mistakes I wrote, please correct me and tell me the correct sentence. I thank you in advance. ^^

"At the same time, I think I can know different cultures friends in the world."

-When you said, "I can know," did you mean to say something like 認識? I asummed you did, so I rewrote your sentence in a way that I would usually express/say that idea. 

Your English is good! Good job!
