form a channel of communication

I got a e-mail from my friend who lives in Yukon.

She made her e-mail adress from my e-mail adress.

When I looked it, I was awfully happy.
Because her e-mail adress is copied from mine.
And she said,
In English, we say imitation is the highest form of a compliment.

The word light up with delight twinlke down on me.
