How to contact IM clients ?

[dirty_phone_girl]

Hi

Just wondering if anyone knows how to do this.....I had an IM chat,  my internet dropped out (I am switching providers on Monday due to issues) and now I am back online and its all ok I cant contact him.

Is there a function somewhere that I can click on his name and it will open an email box ?

I have tried searching his name but he doesn't have a profile so I guess it wont come up that way.

Thank you
