Hi!
DFF is an absolutely astonishing project. Great work, Dave!
Still writing to the user's wall is not yet possible trough actions and triggers (Drupal 6.x, current DFF).
In particular the "fb_action" dialog isn't saving anything but the actions name.
I guess that part of DFF isn't yet ported to 6.x. Any plan when it will be? Any workarounds?

Drop me a mail, if you need some helping hands for testing, debugging or documentation.
