Not only did they create the email for us, but they automatically overdid the individual email addresses that we put into our profiles making their email the default.
Most people don't notice the difference since they generally receive regular email from their contacts and Facebook email through their inbox online.
However, if Facebook is not your primary choice in communicating with the outside world (aka your customers) you may want to make sure they have access to your preferred email address through your profile.
How does one do that? It's easy:
Go to your profile, and click on the "About" Section under your profile photo.
Find where it says contact information and take a look. If you still want to edit it, click "edit" and enter in the correct information.
Be sure to click "save" and there ya have it! Done!
