Mormon.org has lots of great information about the Church for people don’t know much about it. Why not help in the missionary work by linking to it from everyone one of your e-mails. Most e-mail services and programs allow you to set up a signature (a phrase that is included in everyone of your emails). You can set it up so it has a link to Mormon.org.
I would suggest only doing this with your personal e-mails. I’m sure most businesses have policies against proselyting or discussing religion at work. So use this with discretion.
