Up at the top of your screen you should see the search bar and then directly under it (if you have invites) you'll have text that looks like this:

Show search options Create a Filter Invite a Friend

Almost just like that.

You first need the name (any name works fine) and *CURRENT* email address of the person you want to invite. You just put that into the little boxes that come up and click okay and it'll say something like "Invite Sent".

When they finish registering, you'll get a little note and they'll be automatically added to your address book.
