your magnolia server does not send any information about your content, not even a link. it simply calls our website saying that someone had logged in OR magnolia has been started. well, we did this because we wanted to know how many people are using magnolia (90% users never post anything on the list) It helped us to know how much effort to put in future development.
hear, hear. another faux-pas (the first one being to claim JCR compliance) from the boys at obinary.
