Quand on pose une question, il faut y répondre! Après être connecté à l'italki, je trouve que ce site est l'un des meilleurs sur l'Internet que je n'ai jamais vu.

Hi Berberiste,

I think italki will be a good place to find friends for language exchanges. I will be happy to talk to you. That way, your English proficiency bar wil go up!

Here is one American English phrase for you: "to have a blast" - to have a lot of fun or enjoy an activity very much

Example:
"Hey Mom! Last night I found this really cool website called italki. I can talk to people all over the world, download resource files, and ask individual questions. I was up until 3 in the morning. I had a blast.

Possible Explaination: the word blast is related to the word explosion. When a bomb explodes, the force is powerful and large. When you "have a blast," you are enjoying your activity so much that your happiness is very obvious to other people. A similar expression might be. "I had a great time" or "I enjoyed myself very much."
