Causes is like a Facebook Fan Page but for charities although its no substitute for a Fan Page it can be a useful extra tool to help you find new supporters.

To get started you register your cause, then invite your friends to join each friend that joins generates a social action for their friends to see.

Each member of the "Cause" can be sent a thank you note if they invite friends, you can give them "props" for the support (each of these generates an action in that users social stream great advertising)

Tip: Wait a few days before sending a thank you or a props, this prompts the supporter and also catches any of their friends that might of missed their initial interactions.

You can send emails to all your Cause supporters:

Causes admins can send emails to all supporters but supporters have to enabled the email opt in or they will never receive it.

Announcement instead:

To work around this problem causes also includes and announcement option in fact I would suggest using announcements in addition of the email option. An announcement appears in the users home screen not in their inbox, on Facebook the benefit of this is users don't see them as spam more as a feature of the Facebook profile. Even so don't abuse it but it can be a much more powerful and inoffensive way of getting the word out about a given project or event.
