Need urgent help locating A facebook or Twitter profile for this email?

[john]

I've tried sending mail to that address but it always said '' failure notice '' and the message isn't delivered .
I need someway to communicate with that person .

fred : didn't know that , I'll edit it . the error message is : failure to send couldn't deliver the message to the following recipient , p.s that person gave me his email address to locate him and communicate , my guess is he didn't sign on his mail for too long it got closed , I want to know if there's anyway to locate him on an active communicator like facebook etc ..
daniel : I've already tried that with no luck at all , yet I know for sure that this is the email he made his profile with , simply cause he told me so .
p.s the problem that this person isn't well experienced in electronic communications that's why its difficult to locate him till now .
