Discuss PGroot's answer to: How to forward non email?

Do you mean how to forward postal mail?  For first class mail in the US you can write on the envelope "please forward to" and give the new address.  Or if you are moving, you can have the US Postal service forward your mail for 6 months.

It wouldn't be a "forward" if wasn't a mail of some kind.  Do you mean that you want to send a document or a picture by email?  You can attach a file (or several files) to an email.
