How do i email youtube?

How do I find an email through a youtube username ?

• I cant find my friends email ... He has been grounded and cant get online ... I tried asking him at school ... but he has a bunch of numbers in his email and he has to see his email and write it down ... He said if i could find a way to use his username to find it out i could. But i cant figure out how ! Does anyone know a place were i can enter his youtube username and get his email ????????

• Answer:

  I don't think the privacy settings will allow that. When you send him a message on his youtube profile he should probably get an email though, so you can use that, you just can't put private stuff in it, but he can email you if you put an address in it, just make a free address somewhere so you don't have to give up your private address.
