BuddyPress.org

Does anyone know how to get a welcome email in BP 1.1.3 without resorting to the Welcome Pack plugin?

There are some clues here, but I have no idea what to do with them and if this would even apply to Buddypress registration process.

Should I just stick this in a template files somewhere? Where?

<?php wpmu_welcome_user_notification($user_id, $password, $meta); ?>

Would it take the text from the Options in the admin area?

Or does BP have its own function for this?
