I'm still learning new things everyday about my new Mac, but now I'm stumped again. I created a word document using Pages and everything was easy. It was very similiar to Microsoft Word. But I saved the file and sent it out in an email, and nobody can open the file. I sent a copy to my work PC and it came as a .pages document. What did I do wrong? Is there a process I missed to make it a pdf or doc file?
