翻译下。。。聊天中的 随意点翻译。。谢谢

I can only know about your life from your MSN/QQ signiture.

或者引申一点的意思，可以表达为
May I know more about your life except from your QQ/msn signiture?
(除了你的签名以外，你可以让我了解更多关于的你生活吗？）

I can know you and your life from your signatures on MSN or QQ only.

I only can get to know you (your life ) from your signature on MSN or QQ.

From your signature to know your life

The only way I know you and know your life is from your self-introduction.

不是机译的可以用

I just know you lifestyle through your signature .
