I use the E Cards and send messages Via the Genealogy Tab Weekly.
I also have a training page at face book. With a training group set up at Skype.
I give all my down line my face book link. Telling them to check back often.
I also tell them to connect with me at skype, where I will add them to our Training group. This way all my team can connect with each other. Showing support when I am off line. Team support is the key.
