Send one electronic message to each partner either via this page or using the email. Use animoto.com ,voki.com or anything else you like. Here is a link on how to embed voki as with the new space it is slightly trickier. Animoto still free but unfortunately voki is only partly free. You can still create avatars for free but need an upgrade to embed it.
