I only use Facebook as an alternative to OpenID but sometimes need to send a private message to someone I'm not friend with.
I checked the "Sending a Message" page on Facebook, which says:
Start typing a name or email address into the To field. Names of friends and other people you know will appear in a dropdown
How can I find the name or email address? I didn't find this on someone's FB page, and just copy/pasting the FB name doesn't work:
Do I need to be friend with someone before being able to send them a private e-mail?
