A Few More Tips
There are a couple of things that you'll want to be aware of as you are following this procedure. After you convert your Pages document to a Word format, open the document in Word (if you can) to verify that nothing has been lost in the conversion. I would specifically check things like spacing, indentations, blocked quotes, and special characters. I've had issues with some of these in the past, especially blocked quotes when it came time to print. Just take the time to double check.
Also, if there is ever the option on a later version of Pages that prompts you to save as either a .doc or .docx, it would be a good idea to choose .doc unless you are certain that the person that will be opening this file uses Word 2007 or later. Prior versions of Word will only open .doc files, not .docx (crazy, I know, right?). So, until the newer versions of Word become more ubiquitous, I would suggest playing it safe with the .doc designation. We don't want to run into any compatibility issues.
If you're having trouble figuring this process out, please feel free to leave a comment and ask any questions that you have. But, once you do this once or twice, you won't have any problem at all turning your Pages Files into Word documents.
