I've created an awsome 3D Edge 540, I'd like to send it to people. Does anybody know exactly how I can e-mail this plane to others?

I already did the following. I went to my computer and clicked on c drive, then I clicked on program files, then I went to realflight. I clicked and that and then I clicked on planes. I found my plane and sent it to my documents. Then I wrote an e-mail and attached it to the e-mail. Everybody gets a funny message that they can't read the file.

thanks

John

p.s this plane is absolutly awsome!
